摘要
本文采用微波吸收相敏检测技术 ,得到了卤化银微晶的自由光电子与浅束缚光电子的产生与衰减曲线 ,对比光电子产生量与激发光强之间的关系 ,验证了Gurney Mott理论的光吸收过程 ,分析了不同类型卤化银材料中光电子的衰减特性 ,讨论了卤化银微晶中光电子行为对其感光性能的影响。
The action curves of free photoelectrons and shallow-trapped electrons in silver halide microcrystals were obtained by microwave absorption phase-sensitivity detection technique. Through comparing the relationship between electron numbers and exposure intensity, the theory of Gurney-Mott optical absorption was verified. The electronic decay properties in different silver halide microcrystals were analyzed and the effects of electronic behavior on the sensitization properties in silver halide microcrystals were discussed.
