Abstract
766,416. Photo-electric devices. STANDARD TELEPHONES & CABLES, Ltd. Feb. 4, 1955 [Feb. 12, 1954], No. 3365/55. Class 37. [Also in Group XL (a)] The support-plate of an electroluminescent radiation amplifier is formed with V-shaped grooves with a terminal conductor along the apex of each groove and a strip coating of photoconductive material on the walls of the grooves contacting the electroluminescent layer at the base end. The transparent support 1 is formed with V-shaped grooves 9 with crests 10 and valleys 11, the width of the crest 10 being greater than that of the groove 9. The orifices 12 of the grooves are filled or coated with platinum or silver and form electrodes connected together at the ends by a bus-bar. The surfaces 10, 11 of the grooves are coated with photo-conductive material, e.g. cadmium sulphide, applied preferably by evaporation. The remainder of the grooves 9 is filled with dielectric material 15, e.g. a wax opaque to light. A layer of electroluminescent material 4 is applied along the crests 10, over the photo-conductive material and the wax 15, followed by a transparent electrode layer 5, e.g. silver or stannous chloride. The layers 4, 5 may have previously been applied to the surface of a glass plate. In a modification the plate 1 has its external surface formed as cylindrical lens portions in optical registry with the grooves 9, and causing incident light to converge on to the latter (Fig. 5, not shown). Alternatively, as in Fig. 6, V-shaped grooves 19 are filled with metallic silver 20 which reflects incident light 21 on to the photoconductive layers lining the walls of the grooves 9. Where metal is used on the crests of the ridges it is divided longitudinally by strips of insulating material to produce a mosaic of individual discrete areas (Fig. 8, not shown). In Fig. 7, there are two sets of V-grooves and small segments or films 26 of metal bridge the wide grooves 24 which are filled with the strip conductors 12, photo-conducting material 14 and insulating material, and the adjacent narrow grooves 25 are left empty or filled only with insulation material. The groove 24 may itself be multi-grooved or undulating.
