中文摘要：
为进一步提高有机电致发光器件（OLED）电子载流子的注入水平,简化制备工艺,采用Ca：Mg：Al三元合金作为OLED阴极,制备了结构为ITO/MoO3/NPB/TCTA/CBP：GIr1/TPBi/Alq3/Mg（x%）：Ca：Al的绿色磷光OLED,分析了Mg在提高器件电子注入水平、平衡载流子浓度中的作用及其原理。实验通过优化合金阴极中Mg的含量,得到了亮度为41 830cd/m2、电流效率稳定在26cd/m2左右的高效稳定的绿色磷光OLED。
英文摘要：
Due to the electron carriers′lower mobility and injection than hole carriers in regular organic light-emitting devices（LEDs）,in order to improve the performance by enhancing electron injection and simplify the preparation process,we take Ca：Mg：Al ternary alloys as cathode in organic light-emitting devices and prepare a series of green phosphorescent organic light-emitting devices with structure of ITO/MoO3/NPB/TCTA/CBP：GIr1/TPBi/Alq3/Mg（x%）：Ca：Al.We compare devices with/without Mg in its alloy cathode and analyze the function of Mg in electron injection and balance of hole and electron carriers.We also optimize the cathode by adjusting the content of Mg in ternary alloy cathode,thus maintain devices with maximum luminance of 41 830cd/m2 and excellent current efficiency around 26cd/m2.
