Abstract

Abstract: Microwave Absorption Technique(MWA)is used to study the influence of spectral sensitization on electron decay characteristics in silver halide emulsion.For cubic and tabular grains AgBr crystals,the corresponding relation between sensitization condition and photoelectron decay time is discussed.The best dye sensitization parameter including dye type and dye concentration,which result in high photographic efficiency,is obtained.There is a comparison between sensitized cubic grains and tabular grains emulsion crystals in photoelectrons characteristic.For dye sensitized tabular grains AgBr emulsion,the free photoelectron lifetime is in principle smaller than for cubes.The photographic efficiency of former is higher than the latter.

Key words: microwave absorption, photoelectron lifetime, spectral sensitization
