Abstract
713,916. Electro-luminescence. AMALGAMATED WIRELESS (AUSTRALASIA), Ltd. Sept. 12, 1952 [April 9, 1952], No. 22993/52. Class 39(1) [Also in Group XXXVI] A light amplifying cell for cathode ray tubes and television systems comprises superposed layers of photo-conductive and electro-luminescent substances located between transparent electrodes. A transparent supporting plate 11, e.g. of glass, carries a transparent conducting electrode 12, a thin layer of an electro-luminescent material 10, a thin layer of photo-conductive material. 13 and a second electrode of transparent conducting material 14 in that order. The relative position of plate 11 is unimportant and there may be two such plates one with each conducting layer. The conducting layers are connected to the terminals of an alternating voltage source, the magnitude and frequency of which determines the intensity and colour of the light emitted by the layer 10. The photo-conductor may be antimony trisulphide which has a saturation effect in the relation between photocurrent and illumination and may compensate the exponential relationship of the electro-luminescent material. An opaque conducting layer between layers 10, 13 prevents reaction between the layers, but it should have high lateral resistance e.g. it may be a mosaic of small metal islands. Controlled feed-back may be utilized to increase amplification. Selenium and cadmium sulphide are also suitable photo-conductive materials, and the electro-luminescent material may be a fired mixture of three parts zinc sulphide and one part zinc oxide activated by 0.75 per cent copper or lead. This phosphor mixed with nitro-cellulose gives greenishyellow at 50-60 cycles and blue luminescence at 2000 cycles of the applied alternating voltage which is between 25 volts and the breakdown voltage of the material.
