摘要
对以Al/Alq3 /TPD/ITO/玻璃结构的有机 /聚合物发光二极管 (OLED)为发光器件 ,以光电二极管和双极晶体管构成的复合光探测器为光接收器件组成的光耦合器进行了实验研究。通过改变OLED上的偏压 ,获得光耦合器输出特性相应的变化。对实验结果进行了分析讨论。
By taking Al/Alq 3/TPD/ITO/glass organic/polymer light emitting diode(OLED) as a light emitter and a integrated photo-detector formed by photo-diode and bipolar transistor as a photo-receiver, a novel opto-isolator has been constructed which is investigated experimentally. The corresponding change of the output characteristics of the opto-isolator is observed by changing the bias of OLED. The experimental results are analysed and discussed.
