摘要/Abstract

摘要： 最近,在国外文献中开始出现新型中空卤化银微晶制备方法的报道^[1-6]。综其所述,中空卤化银微晶与常规微晶相比,具有以下优点:(1)节省贵重金属银的用量,可达到降低成本的目的;(2)具有高的表面积/体积比,从而具有更高的吸光效率;(3)由于比表面积大,可吸附更多的光谱增感染料及其他有用的照相有机物;(4)显影速度快。这些特点都可使中空颗粒乳剂在不增大颗粒尺寸的前提下提高乳剂的感光性能。

Abstract: Several kinds of hollow silver halide microcrystals were prepared by the methods of halogen displacement and epitaxial growth. The holes in the hollow silver halide microcrystals were observed by Scanning Electron Microscope. It is found that by the means of Br-I and Cl-I halogen displacement, hollow grains can be formed when relatively small amount of KI is added to the system, while of Cl-Br displacement, hollow grains appear only when theoretical degree of displacement is higher.

Key words: hollow silver halide grains, emulsion preparation
