摘要
以四苯基二胺衍生物（ＴＰＤ）为空穴传输材料，以蓝光染料酚基吡啶铍（ＢｅＰＰ２）、黄光染料红荧烯（Ｒｕｂｒｅｎｅ）、绿光染料８－羟基喹啉铝（Ａｌｑ３）分别为蓝、绿、红三基色染料，采用多层结构制备了有机多层白光发光二极管．该白光器件的色坐标为（０．３３，０．３６）（在７Ｖ 下），接近等能点白光（０．３３，０．３３）；该器件在１７Ｖ 下的亮度可以达到３０００ｃｄ／ｍ ２， 流明效率为０．３ ｌｍ ／Ｗ。
Organic white LEDs are fabricated by using blue fluorescent Phenylpyridine Beryllium (BePP\-2), orange fluorescent rubrene, green fluorescent Aluminum complex (Alq\-3) as three primary\|color dyes. Diamine derivative is used as hole\|transporting material. The C.I.E coordinates of organic white LEDs are (0\^33,0\^36) at 7V, approaching the equal\|energy white point (0\^33,0\^33). At the applied voltage of 17V, the luminance of the device is up to 3000cd/m\+2 and luminous efficiency is about 0\^3lm/W.
