摘要
用旋涂法实现了多孔硅与聚乙烯咔唑的复合 ,并研究了不同温度热处理后复合体系的电学和光学性能 .实验结果表明 :热处理有利于复合体系发光强度的提高 ;而且当热处理温度不超过 12 0℃ ,随着热处理温度的升高器件的整流效应增大 .同时 ,复合体系还实现了电致发光 ,产生了 5 5 5nm的电致发光峰 .
The composite of porous silicon and poly (9-vinylcarbazole)(PVK) is fabricated by spin coating.The optical and electrical properties of the composite are studied after annealing at different temperature.The experiment results show that the photoluminescence intensity and rectifying characterization of the composite are improved by the annealing at lower than 120℃.Furthermore,the 555nm electroluminescence is produced by the composite.
