Abstract

827,059. Photo-sensitive devices. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 27, 1956 [Feb. 15, 1955], No. 4407/55. Class 37. In a method of producing a photo-sensitive device in which photo-conductive layer is evaporated on to a support from a metal member, the member is coated with a substance which is inert to the photo-conductive material. The Figure shows a television pick-up tube the target of which comprises a translucent signal electrode 3 on a glass base 1 with a first porous photoconductive layer 4 and a second solid photoconductive layer 5. Between electron gun 6 the target is a tubular anode 7 having its end covered with mesh 8. As described in Specification 827,058 a tantalum boat 9 containing photoconductive material 10 is heated in an atmosphere of Xenon to evaporate the material partly on to electrode 3 to form the spongy layer 4, and partly on mesh 8 and anode 7. The boat is then removed, the tube evacuated and anode 7 and mesh 8 inductively heated to re-evaporate the material to form solid layer 5. To prevent reaction between the photoconductive material and anode 7, which may consist of a copper-nickel alloy, the inner surface of the anode is coated with an inert coating 13, such as rhodium, platinum or iridium. The photoconductive material may consist of antimony trisulphide, selenium, cadmium sulphide, zinc sulphide or zinc selenide.
