氮化硅酸盐在结构上建立在三维 SiN4 四面体网络上，形成一类非常有趣的材料，具有高热机械性能、硬度和宽带隙。传统上，氮化硅酸盐常被用作结构材料，如磨料颗粒、切削工具、涡轮叶片等。最近，稀土掺杂氮化硅酸盐的发光特性得到了广泛的研究，并开发出了一类新型的发光材料。本文综述了氮硅酸盐荧光粉的合成、发光和应用，重点介绍了M-Si-Al-O-N（M=Li、Ca、Sr、Ba、La）体系中的稀土氮化物及其在白光LED中的应用。这些荧光粉表现出有趣的发光特性，例如红移激发和发射、小斯托克斯位移、小热猝灭和高转换效率，使其能够用作色温可调和高显色指数的白光LED中的下转换发光材料。
Nitridosilicates are structurally built up on three-dimensional SiN4 tetrahedral networks, forming a very interesting class of materials with high thermomechanical properties, hardness, and wide band gap. Traditionally, nitridosilicates are often used as structural materials such as abrasive particles, cutting tools, turbine blade, etc. Recently, the luminescence of rare earth doped nitridosilicates has been extensively studied, and a novel family of luminescent materials has been developed. This paper reviews the synthesis, luminescence and applications of nitridosilicate phosphors, with emphasis on rare earth nitrides in the system of M-Si-Al-O-N (M = Li, Ca, Sr, Ba, La) and their applications in white LEDs. These phosphors exhibit interesting luminescent properties, such as red-shifted excitation and emission, small Stokes shift, small thermal quenching, and high conversion efficiency, enabling them to use as down-conversion luminescent materials in white LEDs with tunable color temperature and high color rendering index.
