中文摘要：
采用锌金属配合物DPIHQZn（（E）-2-（4-（4,5-diphenyl-1H-imidazol-2-yl）styryl）quinolin-Zinc）,将其掺杂到CBP中作为黄光发射层,制备了黄色有机电致发光器件（OLED）,器件结构：ITO/2T-NATA（20 nm）/CBP：x wt.%DPIHQZn（30 nm）/Alq3（40 nm）/LiF（0.5 nm）/Al,研究了4种不同掺杂浓度（x=5,10,15,20）对黄光器件性能的影响,利用黄光发射层中主体材料与客体材料之间能量转移特性,得到了性能较好的有机电致黄光器件.在相同条件下,当掺杂浓度为15%时,其性能在4组器件中达到最佳,在驱动电压为14 V时呈黄光发射,器件最大亮度达到4 261 cd/m2,最大电流效率为0.84 cd/A,器件的色坐标稳定.
英文摘要：
The yellow organic light-emitting device（OLED） was fabricated when Zinc metal complexes DPIHQZn（（E）-2-（4-（4,5-diphenyl-1H-imidazol-2-yl） styryl） quinolin-Zinc） was doped into CBP as the yellow light emitting layer. The structure of device was ITO/2T-NATA（20 nm）/CBP： x wt. % DPIHQZn（30 nm）/Alq3（40 nm）/LiF（0. 5 nm）/Al. The effect of four different doping concentrations（x = 5,10,15,20） on the device performance was studied. Using of energy transfer between the host material and object properties of the yellowemitting layer material,better performance of the yellow organic light emitting devices were obtained. Under the same conditions,its perforance was optimal in four devices when the doping concentration was 15%. The yellow light emission was achieved at 14 V,the maximum luminance was 4 261 cd/m2,maximum current efficiency was 0. 84 cd/A and color coordinates of the device was stable.
