获得了满足全色显示要求的高亮度蓝光电致发光器件。采用双靶脉冲电子束蒸发法制备了BaAl 2S 4：Eu薄膜电致发光器件。在50 Hz脉冲电压下，最大亮度水平为65 cd/m2。由于Eu ~（2+）离子的5d-4f跃迁，在475 nm附近有一个蓝色发射带。BaAl 2S 4：Eu EL器件的国际照明委员会（CIE）色坐标为x=0.12和y=0.10。
The high-luminance blue emitting electroluminescent (EL) devices which have been satisfied with the requirement for full color displays were obtained. BaAl2S4:Eu thin-film EL devices as the new blue emitting EL phosphor was prepared by the two targets pulse-electron-beam evaporation. The maximum luminance level was 65 cd/m2 under the 50 Hz-pulse voltage. The EL spectrum had a blue emission band with a peak around 475 nm due to the 5d-4f transition for Eu2+ ion. The Commission Internationale de l'Eclairage (CIE) color coordinates of BaAl2S4:Eu EL device were x=0.12 and y=0.10.
