PURPOSE:To manufacture a chemically deposited photoconductive film with high uniformity in a short time by heating an aqueous soln. contg. Cd, holding it at a prescribed temp., and adding an aqueous soln. contg. S or Se. CONSTITUTION:An aqueous CdCl2 soln. and an aqueous ammonia soln. are charged into a reaction vessel and held at >=80 deg.C prescribed temp. in a thermostat. A substrate of glass or the like is put in the vessel, an aqueous soln. of a compound generating S ion such as thiourea is added, and the solns. are brought into a reaction at said temp. with stirring to deposit CdS on the substrate to a desired thickness. After finishing deposition, the substrate is pulled up and washed, and a deposited CdS film is obtd. |
