Abstract
Crystals of silver halides which have been grown and annealed in air have always been used for measurements of photoconductivity. Such crystals, which are dilute solutions of silver oxide in the silver halide, have a much greater photoconductive response at room temperature than crystals of the highest purity. The mechanism responsible for the sensitization of the photoconductivity by silver oxide is discussed. The relationship of the model which is proposed to that developed by Newman, Tyler and Woodbury for the interpretation of sensitized photoconductivity in n-type germanium is indicated.
