摘要: 用LB技术在石英和硅衬底上制备了聚乙烯基咔唑(PVK)的固态有序薄膜.荧光光谱研究表明,PVK在膜中的光致发光主要呈现激基缔合物的发射,其中心波长为418nm;表面光电压谱的测试揭示了PVK聚合物膜/p-Si体系具有显著的表面光伏效应.

关键词: LB膜, 聚乙烯基咔唑, 光电导, 表面光电压

Abstract: The solid state films of photo-conducting PVKmaterial were prapared by means of LBtechnique. The fluorescence spectra showed that strong excimer emission of PVKappeared in the films, and the surface photovoltaic spectra revealed that PVKfilms/p-Si have a significant surface photovoltaic effect.

Key words: LB films, PVK, Photoconduction, Surface photovoltage
