Process improving the photosensitivity of a photoconductive composition and thick layer based on such a composition

摘要

Process making it possible to improve the photosensitivity of a photoconductive composition based on lead oxide PbO, characterised in that it comprises an activation stage consisting in heating the PbO oxide powder of alpha phase at a determined temperature under inert atmosphere. Application to the production of thick layers made of photoconductive material. <IMAGE>
