Abstract

本实用新型涉及一种白色电致发光器件,属于电致发光技术。将基板6上有透明导电层5,把YAG:Ce的发光材料4固定于透明导电层表面,钇铝石榴石YAG的发光材料4上面依次是发光材料3、介质层2,背电极层1,最后是保护层7。优点在于:结构新颖,,它可以使白色电致发光器件所发白色发光更加均匀,发光亮度可在原有基础上提高50%,该结构适用于各类EL玻璃器件、EL搪瓷器件、EL塑料器件。

Description

白色电致发光器件
技术领域
本实用新型属于电致发光(缩写EL)技术。
背景技术
目前现有白色电致发光器件,因其采用:橙色与蓝绿色的电致发光材料混合法、有机染料法生产,均存在着发光亮度低,颜色易改变的缺点,即使最近新出现的钇铝石榴石YAG发光转换组合法(申请号00126509.1),其采用YAG材料与蓝色电致发光材料混合,但其所发白色光有不均匀等问题。
发明内容
本实用新型提供一种白色电致发光器件,以解决电致发光器件发光亮度低、颜色易改变和白色发光不均匀等问题。它可以使白色发光更加均匀,发光亮度可在原有基础上提高50%。本实用新型采取的技术方案是:将基板6上有透明导电层5,把钇铝石榴石YAG的发光材料4固定于透明导电层表面,钇铝石榴石YAG的发光材料4上面依次是发光材料3、介质层2,背电极层1,最后是保护层7。
本实用新型的优点在于:结构新颖,,它可以使白色电致发光器件所发白色发光更加均匀,发光亮度可在原有基础上提高50%,该结构适用于各类EL玻璃器件、EL搪瓷器件、EL塑料器件。它包括基板、透明导电层、YAG层、发光层、介质层、背电极层、保护层。
附图说明
图1、本实用新型结构示意图。
具体实施方式
将基板6上有透明导电层5,把钇铝石榴石YAG的发光材料4固定于透明导电层表面,钇铝石榴石YAG的发光材料4上面依次是发光材料3、介质层2,背电极层1,最后是保护层7,其中介质层可以使用二氧化钛、钛酸钡、钛酸锶、钛酸铅的一种及一种以上的混合物,发光层可以使用蓝色电致发光材料,背电极层可以是金属片或导电银浆,保护层可以是塑料、油漆、玻璃等。
