ABSTRACT:
A photoconductive body of antimony trisulfide is coated on one surface with a layer of an insulating material having particles of a conductive metal dispersed throughout. When used as a target for a vidicon type camera tube, the metal particle-containing insulating layer lowers the dark current of the tube without affecting the photocurrent or spectral response.
