以铟锡氧化物 (ITO)为透明电极 ,8 羟基喹啉铝 (Alq3)为发光层 ,研制成ITO/Alq3/Al结构有机电致发光器件 (OLED) .测量表明其载流子的注入满足隧穿理论 ,发光阈值电压～ 1 2V ,所发绿光在正常室内环境下清晰可见 .通过电流随时间的变化测量了器件的工作寿命 ,并对影响器件寿命的原因作了分析 .
An ITO / Alq3 / Al structure organic electroluminescent device (OLED) was fabricated by using indium tin oxide (ITO) as a transparent electrode and aluminum quinolate (Alq3) as a light emitting layer. The measurements showed that the injection of carriers satisfied Tunneling theory, the luminescence threshold voltage ~ 12V, the green light emitted in the normal indoor environment can be clearly seen through the current measurement of the working life of the device over time, and the factors that affect the life of the device were analyzed.
