Abstract:Silver halide microcrystals, the basic element in photographic products, are commonly reacted with labile sulfur-containing compounds to increase their photographic efficiency (speed). Such "sulfur-sensitized" AgBr microcrystals have been examined with computational and photophysical techniques. Density functional and lattice-relaxation computations have given estimates of the optical transition energies and the electron-and hole-trapping abilities of a number of small sulfur-containing clusters that may be de… Show more
