| 摘 要： | 测量了氙灯辐照后聚酰亚胺(PI)薄膜的光致发光(PL)强度、PL谱和氙灯辐照后直流高电场下PI薄膜的电致发光(EL)强度、EL谱、XRD谱和吸收光谱,研究了其EL、PL特性与微观结构的关系.结果表明:PI薄膜的PL强度随测量时间呈指数衰减,EL强度随场强呈指数增长;辐照39 h后,PI的预击穿场强为2.56MV/cm,...

| Abstract: | Photoluminescence(PL) of polyimide(PI) thin films irradiated by xenon lamp,electroluminescence(EL) of PI thin films irradiated by xenon lamp under high DC high electric fields and their XRD patterns,absorption spectra were measured.The PL intensity shows an exponential decay with the measuring time.The EL intensity shows exponential increase with electric field.After irradiated 39 h,the pre-breakdown electric field of PI is about 2.56 MV/cm,lower than 2.8 MV/cm before irradiation.Both spectra EL and PL spec... |
