Abstract

765,579. Photo-conductive devices. STANDARD TELEPHONES & CABLES, Ltd. June 11, 1954 [June 17, 1953], No. 17293/54. Class 37. [Also in Group XL (a)] An electro-luminescent radiation amplifier comprises a plurality of hollow tubular portions of photo-conductive material the axes of which are substantially normal to the electricallyconducting sheets of the amplifier. The photoconductive material 12 is deposited on the aperture walls 10 of a perforated mesh 11 of insulating material, e.g. of photoform glass, to form a film 2-20 microns thick which does not close the perforations, the plane surfaces of the sheet being afterwards ground or scraped to clean off the photo-conductive material leaving a plurality of insulated tubes of the latter material, the ends of which may be electrically connected to one electrode and the electroluminescent layer respectively. In Fig. 6, upstanding spines 14 on a base 1 of insulating material form evenly spaced crests and valleys, and conductive material 15 is first evaporated or deposited in the valleys, and photo-conduc. tive material 16, e.g. cadmium sulphide on the spines. An opaque material 18 fills the space between the coated spines 14.
