摘要/Abstract

摘要： 5-甲基-7-羟基-1,3,4三氮吲哚嗪(简称稳盐TAI)作为乳剂制备过程的有机稳定剂,已得到广泛应用.一些作者发现,稳盐除了作为稳定剂之外,对部分乳剂还有增感作用.Tani^[1]在硫敏化的立方体溴化银乳剂中加入稳盐,发现可使乳剂的感光度成倍增加,而稳盐对扁平颗粒和八面体颗粒的溴化银乳剂的增感效果较小.

Abstract: The effect of TAI on the size and its distribution of the sensitization centers of the tabular microcrystal of silver halide has been studied by electron micrography.It was found that the size of the S+ Au sensitization centers is concentrated at 48 nm or so.The addition of TAI narrows the S+ Au center distribution and makes them more monodispersed.The monodispersity of the size distribution of sensitization centrer prolongs the photo-electron lifetime .

Key words: tabular grain, size distribution of sensitization center, electron micrography, stabilizer
