Abstract
In one embodiment an improved photoconductor is produced by applying a layer of selenium to a substrate, and then diffusing arsenic into the selenium layer by an electrolytic process in which the arsenic and the coated substrate are suspended in a heated, fluoride salt bath, and a DC voltage is applied across the arsenic and the selenium layer to effect diffusion of the former into the latter. In another embodiment a layer of cadmium sulfide is applied to a substrate and silver or copper is diffused into the cadmium sulfide layer by an electrolytic process.
Claims7
The method of producing an alloyed photoconductor, comprising
- applying a layer of photoconductive material to a substrate, and
- diffusing an alloying metal into said layer by an electrolytic process, including
- placing the alloying metal and said layer in a heated, molten fluoride salt bath as the anode and cathode, respectively,
- applying a DC voltage across said anode and said cathode, and
- conducting said electrolytic process in an inert atmosphere.
