从有机电致发光薄膜的发光机理出发，通过对单层Ａｌｑ薄膜器件、ＰＶＫ为空穴传输层和Ａｌｑ为发光层的双层薄膜器件以及ＰＶＫ掺荧光材料Ｐｅｒｙｌｅｎｅ的双层薄膜器件的研制，从器件的电致发光谱、电流密度－电压特性、亮度－电压特性的曲线的测试结果，计算分析了器件的流明效率、量子效率，并对有机薄膜电致发光器件的结构与发光特性之间的关系进行研究，利用能级理论分析了器件的发光特性随器件结构不同所具有的规律。实验表明，加入ＰＶＫ空穴传输层后，双层的效率比单层提高了１０～１００倍，最高的量子效率达到０．１５％，流明效率达０．０８ｌｍ／Ｗ，并可以通过调整空穴传输层及发光层的厚度改变器件发光亮度。
Starting from the light-emitting mechanism of the organic electroluminescent thin film, a double-layer thin film device with a single-layer Alq thin film device, a double-layer thin film device with PVK as a hole transport layer and Alq as a light-emitting layer, and a PVK- Device electroluminescence spectra, current density - voltage characteristics, brightness - voltage characteristics of the curve test results, the calculation of the device lumens efficiency, quantum efficiency, and the organic thin-film electroluminescent devices between the structure and the light-emitting characteristics The relationship between the research, the use of energy level theory analysis of the device with the light-emitting characteristics of different structures have the law. Experiments show that, after adding PVK hole transport layer, double layer efficiency than single layer increased 10 to 100 times, the highest quantum efficiency of 0.15%, lumens efficiency of 0.08lm / W, and can be adjusted by holes The thickness of the transmission layer and the light-emitting layer changes the light-emitting brightness of the device.
