Abstract
838,902. Electroluminescence. STANDARD TELEPHONES & CABLES Ltd. Jan. 9, 1959 [Jan. 10, 1958], No. 901/59. Class 39(1). [Also in Group XXXVI] A light amplifier or image convertor comprises a flat grid-like electrode 1, the wires of which are coated with an opaque insulating layer 2 deposited by spraying dipping or electrophorisis, and the upper sides of the wires are coated with a layer of metallic silver or copper deposited by sputtering or evaporation. A number of copper pin-like projections 4 are electrolytically deposited in the spaces between the coated grid wires. The projections extend into a transparent insulating layer 5 which is applied to the pins and may consist of a methacrylic ester dissolved in toluene. The layer 5 is coated with a layer 6 of electroluminescent substance, this layer being provided with transparent second electrode 7 shielded by glass plate 8. The insulating layer and most of the conducting layer on the upper-side of the grid wires are ground away and a photoconductive layer 10 is provided. This layer forms an electrical connection between grid wire 1 and pins 4 when it is irradiated. The thickness of the layer 10 is slightly less than the depth of penetration of the light incident upon it, in this way maximum conductivity variation is attained for each quarter of incident energy, thus giving a good resolution. In operation, if no light falls on layer 10 the amplifier is equivalent to two capacitors in series the electrodes of which are formed by wire 1 and pins 4, and pins 4 and electrode 7. When light is incident upon the layer 10, this becomes conducting and the devices become equivalent to a single capacitor. An alternating potential source, operating with a frequency between 50 and 5000 cps, is supplied to the electrodes 1, 7 by leads 9.
