Churashov V. Principles of creation and property low silver of photographic materials with heterophase microcrystals for radiography and holography.

Тhe principle of creation of composite microcrystals (MC) such as " silverless core - halide silver shell" is offered. The conditions of escalating of a thin photosensitive shell on core are determined at preservation high censitometric parameters halide silver. The substances of core, being as rountgen luminophores, enable to create systems, in which in limits of heterophase MC are combined the strengthening screen and photosensitive phase. The specificity of display of a thin shell allows to reduce amount of silver in a material without loss of information capacity. The received materials do not concede on deffectoscopic and radiographic sensitivity to best screenless to foreign and domestic materials containing much more of silver. Are offered super low grain composite materials and the method of their processings allowing a part of a not silver core to use for record the phase making optical information and to receive the deep three-dimensional passing holograms with high angular selectivity and di ffractional efficiency.
