Description

technical field [0001] The invention relates to the technical field of silver salt photosensitive materials, in particular to a laser holographic ultrafine particle silver salt photosensitive material and a preparation method thereof. Background technique [0002] Traditional silver salt photosensitive materials include nuclear emulsion and Lippmann emulsion. Among them, the particles of nuclear emulsion are fine. In the past, the particle diameter of nuclear emulsion was generally between 0.1-0.4 μm, but in recent years it has shrunk to about 0.1-0.27 μm. The silver halide grains of the Lippmann emulsion are also very fine, with a grain diameter of 0.02-0.09 μm and a resolution of more than 1000 lines / mm. However, the chemicals and components used in nuclear emulsions and Lippmann emulsions are defective, and the halogenation method and measurement accuracy are poor, resulting in large diameter silver halide particles, uneven particle distribution and size, and low resolut...
