采用ＳｒＳ：Ｃｅ作为发光层制备了可用于彩色薄膜电致发光显示的较大面积的蓝色薄膜电致发光显示屏。非矩阵屏在１ＫＨｚ驱动时最高亮度是９００ｃｄ／ｍ２；矩阵屏亮度为３０ｃｄ／ｍ２；矩阵面积为４０ｍｍ×７５ｍｍ，象元数为８０×１５０线，象元面积为０３ｍｍ×０３ｍｍ。ＳｒＳ：Ｃｅ蓝色发光粉是采用Ｈ２法还原ＳｒＳＯ４得到的。对不同的合成方法及结构，Ｃｅ３＋浓度对ＰＬ性能的影响等进行了较系统的分析。
A large-area blue thin-film electroluminescent display that can be used for color thin-film electroluminescent display is prepared using SrS: Ce as a light-emitting layer. The maximum brightness of the non-matrix screen when driving at 1KHz is 900cd / m2; the brightness of the matrix screen is 30cd / m2; the matrix area is 40mm × 75mm, the number of pixels is 80 × 150 lines, the pixel area is 03mm × 03mm. SrS: Ce blue luminescent powder is obtained by H2 method to reduce SrSO4. The different synthesis methods and structures, the effect of Ce3 + concentration on PL properties were systematically analyzed.
