Hybrid dielectric–metal colloid nanoparticle heterostructures have recently attracted attention in both fundamentals and applications. In this paper, we developed a new approach based on mechanical grinding and chemical synthesis in order to obtain hybrid dielectric–metal nanoparticles. By increasing the amounts of the stabilizing agent (polyvinylpyrrolidone (PVP)), three different types of hybrid colloidal structures were obtained, Si/Au core–island, core–shell, and core–shell oligomers heterostructures, respectively. The obtained colloidal heterostructures were analyzed by dynamic light scattering (DLS) and scanning electron microscope (SEM) measurements. Moreover, the optical properties of hybrid nanostructure have been carefully studied. A splitting was observed in the extinction spectra of colloidal solutions for different Si/Au colloidal heterostructures compared to Si colloidal nanoparticles, attributed to the hybridization of plasmon. Thanks to photolitholographic and drop-cast deposition techniques on a substrate, we were able to locate the colloidal nanoparticles heterostructures and to measure the backward scattering spectra using single-particle dark-field scattering spectroscopy. To better understand scattering results, FDTD simulations of scattering cross-section and electric near-field distributions were performed. As is well-known, the scattering spectrum of the pristine Si core is dominated by electric and magnetic dipolar modes in the visible region. More importantly, the scattering spectra of Si/Au core–island and core–shell support several phenomena such as collective magnetic dipolar modes and multiple Fano lineshapes. Our finding highlights the potential of our dielectric–metal heterostructures as a platform for studying light–matter interactions at the nanoscale.

Aiming at the response spectral of organic photodetectors (OPDs), we investigate a method of preparing the narrow-band near-infrared (NIR) OPDs by using thin film transfer print technology (TFTPT) to prepare the active layer of bulk heterojunction on the organic photo-filtering layer—a functional layer which can block some specific wavelengths of light and prevent these photons from reaching the next functional layer. Herein, short-wavelength photons are absorbed by the photo-filtering layer to form excitons, but they cannot be successfully dissociated due to the lack of a dissociation interface to the acceptor for eventual composite annihilation. While long-wavelength photons can effectively pass through the photo-filtering layer to reach the active layer and be absorbed and dissociated into free electrons and holes and eventually realize the narrow-band optical response. A narrow-band NIR OPD is prepared with a response peak of 790 nm and a full width at half maximum of 62 nm. Under the bias voltage of -5 V, the responsivity and specific detectivity of the device at 790 nm are 0.24 A/W and 1.39 × 1012Jones, respectively. The responsivity and specific detectivity of OPDs prepared based on our method can be flexibly adjusted by the combination of different photo-filtering and active layers, and the universality of our method is also proved.

Metal nanoclusters, composed of a few to a hundred atoms, whose size is close to the Fermi wavelength of electrons, have become a new type of phosphor materials due to their unique electronic structure and excellent performance. And metal nanoclusters have been applied in various applications, such as bioimaging, chemical biosensing, optoelectronic devices, etc. At present, researchers have synthesized and studied gold nanoclusters and silver nanoclusters, but Au and Ag nanoclusters have one drawback: expensive. At the same time, copper nanoclusters have attracted people's attention because of their non-toxicity, large Stokes shift and economy. In this paper, we fabricated 1-dodecanethiol (DT)-capped self-assembled copper nanoclusters in colloidal solution with yellow light emission and characterized the prepared self-assembled copper nanoclusters by UV-visible spectra, TEM and PL characterization methods. Self-assembled copper nanoclusters were used as color conversion layers for the manufacture of white light-emitting diodes. The prepared white LED has good color properties, the color rendering index was 79.3, the CIE color coordinates located at (0.3213,0.3255) and the color temperature was 6067K. This indicates that copper nanoclusters show potential for applications in white lighting emitting diodes as a new type of low-cost and superior photoluminescent material candidates.

A highly sensitive, stable electrochemical acetylcholinesterase biosensor with silver-graphene modified was fabricated to detect organophosphorus pesticides, dichlorvos. Complete production and test process were characterized by scanning electron microscopy, cyclic voltammetry, differential pulse voltammetry. The electrochemical signal of biosensor got to be well amplified because of the modification of silver-graphene. The better detection performance was got, compared with the sensors that lack or no modified. Moreover, TiO2 sol-gel and high viscous chitosan were used as a highly efficient immobilization matrix for immobilizing acetylcholinesterase. The detection linear range of the biosensor to dichlorvos, a model organophosphorus pesticides compound, was from 0.036 μM (7.9 ppb) to 22.6 μM, with a limit of detection of 7.4 nM (1.6 ppb). The biosensor was highly reproducible and stable in detection and storage.

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade. © 2023 The Authors.

We have found that some fluorescent small molecules could be used as donor in organic Schottky junctions (OSJs) and achieved good performance. There has been no report on the application of thermally activated delayed fluorescence (TADF) luminescent material on OSJs. In this work, the effect of TADF isomers on the solar cell performance and dielectric characteristics of the OSJs were investigated. All the doped OSJs demonstrate higher Jsc than the neat C 60 OSJ, and 4CzTPN achieves the highest photovoltaic performance. However, the overall efficiency of these OSJs is not so high probably arising from the high photoluminescence quantum yield of these donors. The dielectric characteristics including Z-V, C-V, and Z-f were investigated, and the Z-V characteristic shows a reverse trend with the Jsc. For the C-V characteristics, the first V peak demonstrates a similar trend with the open circuit voltage and the built-in potential. The 4CzPN OSJ depicts much higher capacitance for the second peak than the 4CzIPN and 4CzTPN based OSJs, indicating the existence of more traps, resulting in a relatively low Jsc. For Z-f characteristics, the impedance of the doped OSJs is slightly lower from 20 Hz to 10 7 Hz than the neat C 60 OSJ.

Building two-dimensional lattices in semiconductor quantum-wells offers the prospect to design distinct energy-momentum dispersions, including conical intersections and nondispersive bands. Here, we compare three lithographic patterning methods, e-beam lithography, block copolymer lithography and thermal scanning probe lithography to produce a honeycomb lattice in an In_0.53Ga_0.47As quantum well. We weigh up the pros and cons of each method to reach lattice constants smaller than 20 nm with a minimum of dispersion in the pore size.

Miniaturization and high-power are the important development directions of electronic components today. The volume of Light emitting diode (LED) is getting smaller and smaller, but the power is increasing dramatically. If the heat accumulated in the device and let the junction temperature of the electronic components exceeds the critical value, the reliability and lifetime of the device will be reduced markedly. Diamond-Like Carbon (DLC) films have high hardness, high wear-resistance, high thermal conductivity, high insulation and so on, and have been widely used in mechanical, electronic, optical and medical fields. This study focused on the effect of radiation heat transfer in the heat dissipation of high-power LEDs, DLC films were deposited on the packaging substrates of LED lamps, and the thickness influence of DLC films on the heat radiation performance was investigated by Infrared thermal imager. The LED models were established by using Solid-Works drawing software, and the thermal simulation analysis of LED with different thickness of DLC films was carried out by ANSYS. The experimental results show that the surface temperature of the LEDs with 1.6, 2.4 and 3.2 thick DLC films on the aluminum substrate is 1.2, 1.5 and 2.3°C lower than that of the LED without DLC film, respectively. The simulation results are consistent with the experimental results, indicating that thicker DLC film has better effect on increasing the thermal radiation of the substrates.
