摘要

A new green EL phosphor with excellent brightness, efficiency, and color-saturation was developed. This phosphor is based on europium-activated Calcium thioaluminate materials system. The performance of this phosphor is enhanced remarkably by the addition of Gd as a co-dopant. The luminance of the EL devices can be as high as 1700 cd/m~2 with CIE color coordinates (.190,. 645). The device efficiency is over 2 1um/W.
