分散型电致发光(EL)器件的开发及照明应用

Development of Powder Electroluminescence Device and Its Lighting Application

分散型电致发光(EL)是将无机荧光体粒子分散于有机聚合物的荧光体层,并将功能性的胶体层叠积成基本单元,通过印刷加工实现器件化的新光源。但色纯度和亮度低,新开发的混合式EL器件中融合了色纯度优的有机色素,是具有高亮度、高显色性和高附加值的新型面光源发光器件。

The powder EL is new light-source, which disperced in fluorescent layer of organic polymer by in- organic fluoresce particle, and laminated basic element by functional colloid layer, and realizable photo-de- vice by print-process. However, the colour-rendition and the brightness both are low. Hybrid EL device de- velopment lately, is eombinated with high colour-rendition. It is new plat-light source organic-pigment had high brightness and high colour-rendition and high attach-value.
