稀土离子掺杂的三元硫代酸盐硫化物满足薄膜电致发光荧光粉的电学和光学要求。这些材料代表了全彩色电子发光显示器的突破。当掺杂Ce3+时，srga2s4提供深蓝色发射，而当掺杂Eu2+时，srga2s4提供饱和绿色发射。本文综述了Ce3+和Eu2+在srga2s4化合物中的一些发光特性，并介绍了制备这种三元化合物薄膜的各种技术。讨论了电致发光器件的行为和性能。
Ternary thiogallate sulphides doped with rare-earth ions fulfill the electrical and optical requirements for thin film electroluminescent phosphors. These materials represent a breakthrough in the achievement of full colour EL displays. SrGa2S4provides a deep blue emission when doped with Ce3+and a saturated green with Eu2+. Some luminescent properties of Ce3+and Eu2+in SrGa2S4compounds are reviewed and the various techniques used to prepare thin films of this ternary compound are presented. The behaviour and performances of EL devices are discussed.
