摘要: 中空卤化银微晶制备方法已在国内外有关文献中报道[1~7],然而关于中空立方体颗粒乳剂的基本性能及实际应用方面的研究尚未见报道.本文主要制备了中空立方体AgBr(Cl)乳剂,应用表面显影、化学增感方法,并与立方体AgBr和实心立方体AgBr(Cl)乳剂进行对照实验,研究中空卤化银微晶的结构和感光性能的关系,证明中空立方体颗粒乳剂的感光性能优于立方体颗粒乳剂.

Abstract: The hollow cubic silver halide microcrystals were prepared. The relation between structure and property of the hollow cubic microcrystal emulsions was studied by means of surface development and chemical sensitization. The results show that the latent image is always formed preferentially around the holes of the hollow cubic silver halide microcrystals. Compared with solid cubic AgBr and AgBrCl emulsions, the hollow cubic grain emulsion has higher surface reaction activity and higher sensitivity. The advantages of hollow cubic silver halide microcrystals can be ascribed to their unique hole structure.

Key words: silver halide emulsion, hollow cubic grain, photographic property
