采用双源电子束蒸发技术在iFire衬底上制备了一种高亮度无机电致发光（iEL）蓝色荧光粉，即掺铕的MgxBa1−xAl2S4。使用120Hz双极脉冲方波形式，颜色性能为L60 >200 cd/m2, CIE x， y坐标分别为0.135和0.105。镁对钡的部分取代降低了BaAl2S4荧光粉结晶的退火温度，这是制造大尺寸无机电致发光器件（如大屏幕电视）的重要参数。
A high luminance inorganic electroluminescent (iEL) blue phosphor, europium doped MgxBa1−xAl2S4, has been developed on iFire substrates using dual source electron beam evaporation. The color performance is L60 >200 cd/m2 with CIE x, y‐coordinates 0.135 and 0.105, respectively, using a 120Hz bipolar pulsed square wave form. Partial substitution of magnesium for barium lowers the annealing temperature of BaAl2S4 phosphor for crystallization, which is an important parameter for fabricating large size inorganic EL devices for such applications as large screen television.
