摘　　要：基于有机发光二极管的电致发光原理,建立了载流子注入延迟时间和发光延迟时间模型,探索了延迟时间的影响因素,发现发光延迟时间与器件有效面积、器件厚度、外加电压等密切相关。通过制备不同面积的OLED器件,发现器件面积越小,发光延迟时间越短。以高速信号激励不同面积的OLEDs器件,面积为0.01 mm2的器件能够实现1 000 Mbit/s的信号传输速率,且能量利用率达到47.7%。Based on the principle of organic electroluminescence（ EL）,models of carrier injection delay time and EL the delay time were developed. The results show that the EL delay time is significantly related to the light-emitting area,the thickness of organic layer and the applied voltage. By preparing organic LED devices with different areas,it is found that the light emission delay time is shorter when the device area is smaller. Furthermore,excited by high-speed signals,the OLED device with an area of 0. 01 mm^2 is effective under the excitation with a frequency of 1 000 Mbit / s,leading to an energy utilization rate of 47. 7%.
