中文摘要：
合成了一种新型有机小分子发光材料10-羟基-苯并喹啉（Bq）,利用电化学循环伏安方法测量了此材料的能带宽度为1.98 eV左右,此材料的光致发光峰位于616 nm,这个数值与材料能带宽度相吻合。利用高斯03软件计算了此材料分子的最高分子占据轨道和最低空轨道上的电子分布情况。将此材料与聚乙烯咔唑（PVK）按3%的质量比配成混合溶液,制备出了ITO/PVK：Bq/BCP/Alq3/Al和ITO/PVK：Bq/Al结构的电致发光器件,测量了这两种器件电致发光谱,除了位于616 nm的Bq的发光峰,同时在500 nm处还存在一个发光峰。经分析认为500 nm的发光峰源自PVK和Bq分子间的电致激基复合物发光。多层结构的器件在不同电压下都呈现白色的发光,经计算发光的色坐标为（x=0.37,y=0.38）。
英文摘要：
A new kind of organic luminescent material 10-Hydroxybenzo[h]quinoline（Bq） was synthesized.The band gap of this material is about 1.98 eV measured by electrochemical cyclic voltammetery.The photoluminescence emission peak was about 616 nm,which was in accordance with the cyclic voltammetry experimental results.The electron cloud of the highest occupied molecular orbit and the lowest unoccupied molecular orbit were calculated by Gaussian 03 software.The organic material Bq and polymer poly（N-vinylcarbazole） PVK were dissolved into chloroform according to the weight ratio of 3%.Two kinds of devices ITO/PVK：Bq/BCP/Alq3/Al and ITO/PVK：Bq /Al were fabricated.There was not only 616 nm emission from Bq exaction,but also a peak at 500 nm emission in the electroluminescence spectra.The emission peak at 500 nm should be attributed to the electroplex emission（bimolecular emission） from PVK and Bq molecule.Based on the multilayer devices,the white emission was obtained under different driving voltages and the emission coordinate was about（x=0.37,y=0.38）.
