The substantial amount of data generated every second in the big data age creates a pressing requirement for new and advanced data storage techniques. Luminescent nanomaterials (LNMs) not only possess the same optical properties as their bulk materials but also have unique electronic and mechanical characteristics due to the strong constraints of photons and electrons at the nanoscale, enabling the development of revolutionary methods for data storage with superhigh storage capacity, ultra-long working lifetime, and ultra-low power consumption. In this review, we investigate the latest achievements in LNMs for constructing next-generation data storage systems, with a focus on optical data storage and optoelectronic data storage. We summarize the LNMs used in data storage, namely upconversion nanomaterials, long persistence luminescent nanomaterials, and downconversion nanomaterials, and their applications in optical data storage and optoelectronic data storage. We conclude by discussing the superiority of the two types of data storage and survey the prospects for the field.

The global data explosion has heightened the demand for advanced optoelectronic information storage technologies but developing multidimensional and deep-trap persistent luminescence (PersL) in organic storage media remains a significant challenge. Herein, donor-acceptor-donor wedge-shape thermally activated delayed fluorescence emitter 2,5-bis(4-(diphenylamino)phenyl)-7-oxo-7H-benzo[de]benzo[4,5]imidazo[2,1-a] isoquinoline-10,11-dicarbonitrile (TCN) is designed for PersL host/guest system, enabling multi-mode excitation and stimulation forms, approximate to 0.72 eV deep trap depth, 6.1% aggregation-induced quenching effect. UV, visible light (425-630 nm), and X-ray efficiently triggered deep traps with nearly identical depth values, deviating less than 0.04 eV from density functional theory calculations. The thermoluminescence peak Tm at 385 K (heating rate at 50 K min-1), coupled with near-infrared (NIR) stimulation wavelengths extending to 1300 nm, greatly exceeds room temperature storage capacities, ensuring consistent intensity for over 1 month of information retention. The multi-mode optical information storage and retrieval capability of this PersL media extended its application scope to include blue-laser direct writing, X-ray time-lapse imaging, and NIR electronic signatures. This study on deep-trap PersL storage media significantly advances the understanding of molecular design and luminescent mechanisms in organic semiconductors, with broad implications for enhancing their energy storage applications in diverse scenarios.

data storage is a commodity in the modern day digital era, which is often overlooked when advances in other fields as AI are headlined. It is forecast, that the demand of storage will surpass the supply, yet there is no solution available to close this gap. Our research aims to revolutionize optical data storage by employing inert data carriers made of thin glass and ceramic coatings, combined with femtosecond (fs) laser technology. This approach offers a cost-effective, energy-efficient, and low-maintenance long-term data storage solution on a Write-Once-Read-Many (WORM) medium. We utilize laser ablation of thin films with ultrashort pulses, enhancing the write/read process through massive parallelization enabled by beam shaping and a Micro-Opto-Electro-Mechanical Systems (MOEMS) device, alongside GigE camera technology. data is stored as physical matrices on ceramic-on-glass sheets and retrieved via an image processing chain subsequent to high-speed microscopy. storage and retrieval were successfully demonstrated in a working prototype, where this technology has already shown significant potential to achieve high writing and reading speeds in the gigabytes per second (GB/s) range. Furthermore, initial media lifetime estimates are promising, reinforcing the viability and durability of this innovative solution. © 2025 SPIE.

Distributed Acoustic Sensing (DAS) has emerged as a groundbreaking technology in seismology, transforming fiber-optic cables into dense, cost-effective seismic monitoring arrays. DAS makes use of Rayleigh backscattering to detect and measure dynamic strain and vibrations over extended distances. It can operate using both pre-existing telecommunication networks and specially designed fibers. This review explores the principles of DAS, including Coherent optical Time Domain Reflectometry (COTDR) and Phase-Sensitive OTDR (phi-OTDR), and discusses the role of optoelectronic interrogators in data acquisition. It examines recent advancements in fiber design, such as helically wound and engineered fibers, which improve DAS sensitivity, spatial resolution, and the signal-to-noise ratio (SNR). Additionally, innovations in deployment techniques include cemented borehole cables, flexible liners, and weighted surface coupling to further enhance mechanical coupling and data accuracy. This review also demonstrated the applications of DAS across earthquake detection, microseismic monitoring, reservoir characterization and monitoring, carbon storage sites, geothermal reservoirs, marine environments, and urban infrastructure surveillance. The study highlighted several challenges of DAS, including directional sensitivity limitations, vast data volumes, and calibration inconsistencies. It also addressed solutions to these problems, such as advances in signal processing, noise suppression techniques, and machine learning integration, which have improved real-time analysis and data interpretability, enabling DAS to compete with traditional seismic networks. Additionally, modeling approaches such as full waveform inversion and forward simulations provide valuable insights into subsurface dynamics and fracture monitoring. This review highlights DAS's potential to revolutionize seismic monitoring through its scalability, cost-efficiency, and adaptability to diverse applications while ident

Exploring the effects of zirconium doping on barium titanate ceramics: structural, electrical, and optical properties

In this study, polycrystalline BaZrxTi1-xO3 (x = 0.00, 0.05, 0.10, 0.15, and 0.20) ceramics were synthesized through a solid-state reaction technique. The effect of zirconium doping on the properties of barium titanate (BaTiO3) was investigated by various characterization tools. The structural and morphological properties of the synthesized materials were studied by X-ray diffraction (XRD), Raman spectroscopy, and field emission scanning electron microscopy (FE-SEM). The electrical properties of the Zr-doped BaTiO3 (BZT) materials were examined by impedance spectroscopy and the optical properties were investigated using UV-Vis-NIR spectroscopy. The XRD analyses of the prepared BZT materials revealed a single-phase tetragonal structure. The inclusion of Zr4+ in the BT matrix did not significantly affect the Raman-active modes, suggesting that the tetragonal crystal structure was retained in the as-synthesized samples. FE-SEM analyses revealed that the grain size initially increased from 49.36 nm to 53.24 nm for x = 0.05 wt% and then decreased gradually for higher concentrations up to x = 0.15 wt% (26.99 nm). The dielectric constant, dielectric loss, conductivity, and quality factor determined from the impedance data demonstrated that Zr4+ addition significantly influenced the electrical properties of BT. The band gap energy, Eg, of the synthesized samples were found in the range of 3.19-3.37 eV, which was calculated from the diffuse reflection data. The experimental results suggest that the BZT ceramic materials are suitable for energy storage device applications.

The traditional CubeSats development model is a one-off build designed to accomplish a specific mission using proprietary hardware and software. The specific mission requirements and associated development costs result in a lack of reproducibility for CubeSats. The Naval Academy Standard Bus (NASB) advances the concept of CubeSat modularity with a design that physically separates a fully-functional standalone 1U bus from an independently-developed 1U or 2U customer payload module with a 10-pin wiring harness serving as the sole electrical interface between bus and payload modules. Residing within the standard bus module the main onboard computer (OBC) handles uplink and downlink communications and connects the NASB to the payload module through two interface boards: the Bus Board and the Payload Interface Board (PIB). Ground commands received by the NASB pass through the Bus Board to the PIB in the payload module, through which they are communicated to the payload via universal asynchronous receiver/transmitter (UART) protocol. Messages and stored data generated by the payloads are stored on a secure digital card within the PIB, to be passed on to NASB and downlinked to the ground station. This modular design allows for independent development of payloads, shortening CubeSat development timeline by eliminating the need for bus development in parallel with payload development. © 2025 The Authors.
