The integration of superior characteristics from individual components achievable in heterogeneous composite plates can be achieved through optimal material configuration and combination methods. This approach results in significant enhancements in physical, mechanical, and forming properties when compared to traditional single metal plates. However, challenges such as prolonged manufacturing cycles and the complexity of coordinating interface characteristics and microstructural properties impede the rapid advancement and widespread adoption of heterogeneous composite plate manufacturing. This study offers a comprehensive overview of the primary forming methods for heterogeneous composite plates, including rolling, extrusion, welding, hot pressing, and additive manufacturing. It addresses current challenges and anticipates potential developmental directions, such as the application of specialized energy field-assisted forming techniques and the design of heterogeneous microstructures. The exploration of new resources, the expansion of innovative concepts, the establishment of novel models, the promotion of new principles, and the adoption of transformative technologies are essential for the breakthrough development of heterogeneous composite plate manufacturing. Aligning with the national innovation-driven development strategy and the requirements of major national projects remains a fundamental objective of this research direction. © 2025 Elsevier Ltd

Erbium as an energy trap center for manipulating NIR-II luminescence of Ho3+ in fluoride towards phonon-based ratiometric thermometry

引用

Photonics Research 2025年第5期13卷 1249-1258页

Thermal quenching has been known to entangle with luminescence naturally, which is primarily driven by a multi-phonon relaxation (MPR) process. Considering that MPR and the phonon-assisted energy transfer (PAET) process may interact cooperatively plays a critical role in conducting the thermal response of luminescence thermometry. Herein, an energy mismatch system of Yb3+∕Ho3+∕Er3+ co-doped β-NaLuF4 hollow microtubes was delicately proposed to combat thermal quenching of near-infrared (NIR)-II luminescence of Ho3+ via premeditated Er3+-mediated PAET processes under 980 nm excitation. Meanwhile, the mechanism of anti-thermal quenching is attributed to the Er3+ as an energy trap center to facilitate the PAET process, thereby enabling a considerable energy transfer efficiency of over 80% between Er3+ and Ho3+ without Yb3+ ions as sensitizers. Leveraging the accelerated PAET process at increased temperature and superior emission, the phonon-tuned NIR-II ratiometric thermometers were achieved based on fluoride beyond the reported oxide host, enabling excellent relative sensitivity and resolution (Sr = 0.57% K−1, δT = 0.77 K). This work extends the significant effect of PAET on overcoming the notorious thermal quenching, and offers a unique physical insight for constructing phonon-tuned ratiometric luminescence thermometry. © 2025 Chinese Laser Press.

Investigation on degradation behavior in citric acid solution for MO-Al2O3-SiO2-B2O3 (M = Ba, Sr) glass and its doped BaTiO3 ceramics

This study proposes an innovative strategy for developing a type of BaTiO3 ceramic, which can degrade in citric acid solution, offering the potential for harmless degradation and recycling of BaTiO3 ceramics widely used in the electronics field. The degradable BaTiO3 ceramic has been designed and prepared using chemically active MO-Al2O3-SiO2-B2O3 (M = Ba, Sr) (MASB) glass. By adjusting the glass content, the dielectric constant of the material increases from 725 to 1480. By investigating the physical and chemical interactions between MASB glass phases and BaTiO3 ceramics, we systematically evaluated the degradation behavior in citric acid solution and the dielectric properties of the BaTiO3 ceramics. The results show that the ratio of [TiO6] units to [TiO4] units in glass phases is a crucial factor in determining the chemical stability of BaTiO3-doped MASB glass in citric acid solution. As the ratio of [TiO6] units to [TiO4] units increases from 0.347 to 0.464, the mass loss rate of the BaTiO3-doped BASB glasses in citric acid decreases from 70% to 36.1%. Through SEM–EDS analysis of the BaTiO3 ceramics, it was found that the degradation of MASB glass phase between the BaTiO3 grains in citric acid solution triggers the structural disintegration of the BaTiO3 ceramics. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2025.
