Improved Silver Halide Crystals for Photographic Emulsion

摘要

The computer controlled multistage synthesis of fine-grained photographic emulsions is described. Scanning electron microscopy was used to investigate the shape and size (10 – 1500 nm) distribution of silver halide crystals in the emulsion. The influence of stirrers in the chemical reactor and also surfactant addition on the emulsion quality was revealed. In the result of the investigation a new method for obtaining of high quality photosensitive materials based on the tabular multicoated silver halide crystals was proposed.
