Atomic force microscopy (AFM) has been used to study monodisperse cubic and octahedral AgBr microcrystals, which are essential components of modern photographic materials. Using AFM, detailed information about shape and surface morphology of these microcrystals can be obtained directly with high lateral, as well as vertical, resolution. Critical emulsion parameters, such as diameter, height, and surface roughness, have been determined for individual microcrystals. The results are discussed with regard to principal questions related to AFM measurements on precipitated emulsion particles.
