Abstract

Silicate transparent microcrystalline glass is widely used as a matrix for rare-earth ions due to its high thermal stability, high transparency, and stable chemical properties. Simultaneously, Tb³⁺ ions exhibit wide absorption cross section, high luminescence quantum efficiency, and sensitive green light spectral conversion characteristics under strong excitation by solar-blind ultraviolet. Therefore, Na₃YSi₃O₉ silicate glass was used in this study, which contains yttrium (Y) in its crystal phase. It belongs to the same group as terbium (Tb) and provides many crystallization sites for Tb³⁺ ions. Due to their identical valence states and similar ionic radii, Tb³⁺ and Y³⁺ ions are easily interchangeable. Therefore, this structure provides great potential for improving the conversion efficiency, photoluminescence efficiency, and UV conversion efficiency of rare-earth ion Tb³⁺. In addition, by integrating the glass composite with a silicon-based photoconductor, we successfully fabricated a solar-blind UV detector device and demonstrate its practical application for UV detection from 180 to 400 nm. Notably, its operation waveband reaches to the deep-ultraviolet (DUV) region and surpasses the reported candidates. The progress not only suggests the glass composite can be constructed into complex device, but also provide a valuable solution for new-generation DUV detectors.

高性能宽带日盲深紫外光电探测器用掺Tb3+透明玻璃复合材料

硅酸盐透明微晶玻璃由于其高热稳定性、高透明度和稳定的化学性质，被广泛用作稀土离子的基体。同时，Tb3+离子在日盲紫外线强激发下具有宽的吸收截面、高的发光量子效率和敏感的绿光光谱转换特性。因此，本研究采用了在其晶相中含有钇(Y)的Na3YSi3O9硅酸盐玻璃。它与铽（Tb）属于同一族，并为Tb3+离子提供许多结晶位点。由于它们相同的价态和相似的离子半径，Tb3+和Y3+离子很容易互换。因此，该结构为提高稀土离子Tb3+的转换效率、光致发光效率和紫外转换效率提供了巨大的潜力。此外，通过将玻璃复合材料与硅基光导体集成，我们成功地制造了一个太阳盲紫外探测器装置，并演示了其在180至400 nm紫外探测中的实际应用。值得注意的是，它的工作波段达到深紫外（DUV）区域，超过了报道的候选波段。这一进展不仅表明玻璃复合材料可以制作成复杂的器件，而且为新一代DUV探测器提供了有价值的解决方案。

期刊介绍： The Journal of Rare Earths reports studies on the 17 rare earth elements. It is a unique English-language learned journal that publishes works on various aspects of basic theory and applied science in the field of rare earths (RE). The journal accepts original high-quality original research papers and review articles with inventive content, and complete experimental data. It represents high academic standards and new progress in the RE field. Due to the advantage of abundant RE resources of China, the research on RE develops very actively, and papers on the latest progress in this field emerge every year. It is not only an important resource in which technicians publish and obtain their latest research results on RE, but also an important way of reflecting the updated progress in RE research field. The Journal of Rare Earths covers all research and application of RE rare earths including spectroscopy, luminescence and phosphors, rare earth catalysis, magnetism and magnetic materials, advanced rare earth materials, RE chemistry & hydrometallurgy, RE metallography & pyrometallurgy, RE new materials, RE solid state physics & solid state chemistry, rare earth applications, RE analysis & test, RE geology & ore dressing, etc.
