首次发现了有机薄膜电致发光器件的光生伏特效应，通过对器件的光电流响应谱的详细研究，分析了不同结构的有机发光器件中的有机半导体之间，以及有机半导体与电极材料之间的半导体接触性质，发现有机发光材料Ａｌｑ３，有机空穴传输材料ｄａｉｍｉｎｅ与金属铝电极之间形成阻挡接触，是电致发光器件发光和产生光电效应的根本原因；而双层器件中有机层Ａｌｑ３与ｄｉａｍｉｎｅ之间的结是双层器件产生高发光效率的原因，正是这种结在双层器件中起了局限载流子和激子的作用，使发光亮度大为提高，结合分区掺杂实验结果，给出了较完善的能带模型．
The photovoltaic effect of organic thin-film electroluminescent devices was first discovered. The photocurrent response spectra of the devices were studied in detail. The relationships between organic semiconductors in organic light-emitting devices with different structures and between organic semiconductors and electrode materials Semiconductor contact properties and found that the organic light-emitting material Alq3, organic hole transport material daimine and the formation of metal aluminum electrode barrier contact between the electroluminescent device is the root cause of light and the photoelectric effect; and double layer device Alq3 and diamine The junction between the two devices is the reason for the high luminous efficiency of the device, it is this junction in the double-layer device played a limited role of carriers and excitons, so that greatly improve the brightness of light emission, combined with the partition doping experimental results , Gives a more perfect band model.
