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.\;
