多结构溴碘化银核壳乳剂的众多优点主要缘于颗粒结构中碘的巧妙应用．首先，正空穴被颗粒内富碘的ＡｇＢｒＩ相所捕获，而电子则被外壳所吸收，使电子与正空穴分离，减少了正空穴与导带电子的复合，从而可以提高乳剂的色盲感光度［１］．其次，多层结构颗粒表面所含的碘提...
The multitude of advantages of the multi-structured silver bromoiodide core-shell emulsion are due to the clever application of iodine in the particle structure. First, the positive holes are captured by the iodine-rich AgBrI phase in the grains, while the electrons are absorbed by the shell, separating the electrons from the positive holes and reducing the recombination of the positive holes and the conduction band electrons, thereby improving the color-blindness of the emulsion Sensitivity [1]. Second, the multi-layer structure of particles contained in the surface of iodine ...
