摘要: 本文以硫敏化的乳剂为对照,研究了硫加金敏化的纯溴化银乳剂中的金与乳剂颗粒中光电子的捕陷的关系。Dember效应和低温发光光谱的测量表明,硫加金敏化的乳剂中的金并没有在曝光过程中对捕陷光电子作出贡献。

Abstract: The relation between gold in sulphur-plus-gold-sensitized pure silver bromide emulsion and photoelectron trapping in emulsion grains was investigated with a sulphur-sensitized emulsion as blank. Dember photovoltage and low-temperature luminescence spectrum measurements show that gold in sulphur-plus-gold-sensitized emulsion adds no contribution to photoelectron trapping during exposure.
