Study on Preparation and Morphology of Silver Chlorobromide Microcrystals in photographic emulsion
E-mail:
The preparation and morphology of silver chlorobromide crystals were studied by double-jetting the reactants into aqueous gelatin solutions. The preparation of cubic crystals of silver chlorobromide was examined by controlling the molar ratio of chloride and bromide ions. When the molar ratio of the two halide ions was 1.0 : 1.75(Cl-:Br-), only cubic chlorobromide crystals were obtained. The presence of a hydrophilic solvent in the aqueous complex solution inhibited the growth of cubic crystals, and converted the cubic crystals to a cubo-octahedron shape with 30 wt% of methanol and ethanol. To study the growth habits of silver chlorobromide crystals, 2-, 3-, and 4-aminophenol silver chlorobromide complexes as a single source precusor for the nucleation of sliver chlororomide crystals were used. The generated silver chlorobromide crystals were cubic, cubo-octahedron, octahedron and tabular in shape. In particular, tabular crystals were only found with the 3-aminophenol reagent, where the crystal size was about 800 rim.
