摘    要:本文利用可控双注仪设计并制备了三种系列共二十种片状多层结构溴碘化银乳剂及其外延体。用X射线能谱仪和电镜验证所所设计的碘离子多层分布和氯化银外延体的位置,研究了它们的光物理性质和感光性能,发现外延AgCl对主体微晶性质的影响随层次结构和外延位置不同有很折变化。

关 键 词:多层结构  卤化银  感光乳剂  感光性

Abstract:A series of unepitaxial and epitaxial multistructure tabular silver halide microcrystals with the same content but different distribution of iodide ions were prepared by double-jetprecipitation. The ditribution of iodide ions and the position of epitaxial AgCl in the micro-areas of a single microcrystal were analysed by the means of Scanning Transmissive ElectronMicroscope(STEM)and X-ray Energy Dispersive Spectrorneter(EDS).It was found thatthe iodide and chlorine ions are distributed in the different microareas of tabular microcrystals as designed.The photophysical and photographic properties were investigatd,The results showed that the influence of epitaxial AgCl on the property of tabular silver halide microcrystals apparently depends on the multistructure of original tabular iedobromide micrcocrystals. Reasonable structure with high utilizing efficiency of photoelectrons as well as withhigh original sensitivity has few contribution to enhancing its sensitivity after being epitaxized.On the other hand,there will cause two results after epitaxizing on the emulsion withunreasonable structure:increasing the efficiency of formation of latent image and increasingthe dispersion of latent image.
Keywords:multistructure tabular silver halide microcrystal  Dember effect  epitaxial emulsion To whom correspondenee should be addressed
