Molecular formula :
nature : from the core and shell of two components, and nuclear and Shell obvious boundaries between the silver halide particles formed by ceramics photographic emulsion, also known as the double emulsion particle structure. Core is generally rich in iodine AgBrI (campact) formed by the shell of solubility than a single big core silver halide (AgCl, AgBr). This double structure particles can be effectively realized photonics and optical cavities are separated to reduce the risk of their compound, thereby enhancing the efficiency of latent image formation. Meanwhile, because the particles are different from the silver halide formed, it can improve the emulsion Spectral flu and sensitivity, the film has good camera performance, stability, performance, performance and preservation of wear resistance properties.
