摘要: 有近160年历史的银盐卤化银乳剂制备的感光材料,到目前为止仍不失为一种优良的信息记录材料。但昂贵的白银的缺乏和消耗,使得节银和降低成本成为银盐感光材料生产中急需要解决的问题。

Abstract: A kind of hollow silver halide microcrystals was prepared by the method of using non-aqueous solvent. The holes in the hollow silver halide microcrystals were observed by scanning electron microscope (SEM), and the preferential latent image formation position of hollow microcrystals was studied by surface development and observed by transmission electron microscope. It showed that the latent image is always formed preferentially around the holes of the hollow silver halide microcrystals, and shrinkage phenomenon was observed before and after the hollow grains were treated with water. The sensitometric results showed that the sensitivity of this kind of hollow silver bromide emulsion is much higher than those of cubic silver bromide emulsion and the emulsion of hollow silver bromide prepared by the method of halogen displacement.

Key words: photographic silver halide emulsion, hollow microcrystal, photographic properties
