Chemical Ripening of AgBr Octahedral Microcrystals
E-mail:
The results of the chemical sensitization study of octahedral AgBr microcrystals with the sizes 0.75 - 1.3 μm in various modes of ripening are presented. Spontaneous sensitization (thermal ripening of emulsions without photographically active additives) has been investigated. The spontaneous sensitization is effected regardless of the type of gelatins during synthesis and chemical sensitization. The influence of both the pBr value of chemical ripening and the adsorption of stabilizers and gold ions on photographic characteristics of emulsions in modes of spontaneous and sulfur sensitization have been studied. The data obtained are compared with the results of the similar investigations carried out with the emulsions containing cubic microcrystals, as well as tabular microcrystals. The peculiarities of photosensitivity centre formation in AgBr (111) microcrystals are discussed in terms of ionic conductivity change during chemical ripening.
