PURPOSE:To obtain photoconductive cadmium sulfoselenide particles causing no aggregation and having smooth surface, high crystallizability, a uniform and simple shape and high sensitivity by activating cadmium sulfoselenide particles withIand III group elements in the periodic table. CONSTITUTION:To 1mol mixed crystals composed of CdS particles and Se particles or cadmium selenide particles are added 3X10<-5>-3X10<-3>molIand III group elements in the periodic table such as Cu and Al and >=20% flux such as NaCl, and they are calcined at 50-600 deg.C to obtain activated cadmium sulfoselenide particles. The particles are recalcined at <=500 deg.C, especially 400-450 deg.C. Thus, photoconductive particles causing no aggregation, having smooth surfaces and slight optical memory, and giving high image quality are obtd. |
