Study of Iodide Distribution in T-Grains and its Influence on the Light Absorption and Electrical Properties of T-Grains

Abstract

T-grain AgBr(I) emulsions with dif-ferent iodide contents and distribution were pre-pared successfully. X-ray diffraction and STEM- EDS measurements confirmed that the iodide distribution in T-grains is non-homogencous. Fur-ther study showed that the light absorption, ionic conductivity and photoconductivity of T-grains are affected by the iodide distribution in the T-grains. The variation of sensitomelric properties of AgBr(I) T-grains with iodide distribution is closely correlated to changes in their light absorption and electrical properties
