微波相敏技术在光学材料特性研究中的应用
Microwave Phase-sensitive Technique Applied in the Study of Characteristics of Optical Materials
摘要
利用微波相敏技术,获得了用硫作不同时间表面处理AgBrI晶体自由光电子和束缚光电子时间衰减信号,分析了光电子衰减时间、电子陷阱效应、光电子寿命、有效陷阱深度及束缚电子转移时间与表面处理时间的关系,获得了最佳的表面处理时间为45分钟,有效陷阱深度为0.255～0.265 eV。
Abstract
By means of microwave phase-sensitive technique, the instantaneous decay signals of free electrons and trapped electrons in AgBrI have been obtained with surface disposition in sulfur for different times. The relationships between disposing time and the decay time of photoelectrons, the effects of electron traps, the lifetime of photoelec－trons, the effective depth of traps and the transfer time of trapped electrons have been analyzed.
