Abstract
1,135,460. Image pick-up tubes; photoconductive elements. RADIO CORPORATION OF AMERICA. 18 Oct., 1966 [15 Nov., 1966], No. 46631/66. Headings H1D and H1K. [Also in Division C7] In a photo-conductive element, such as a target for a pick-up tube, comprising an electrode associated with a photo-conductive layer consisting primarily of selenium and tellurium, the tellurium content decreases uniformly from the electrode face to the opposite face. Typically the electrode is a tin oxide or rhodium deposit on a glass face plate and the photo-conductive layer, which preferably contains arsenic, abuts it. Alternatively, a layer of low work function material such as pure selenium, or caesium or cerium as metal, oxide or selenide is provided between the electrode and the photo-conductor and forms a PN junction with the latter. The vitreous structure of the layer may be stabilized by a layer of suitable material at one or both faces. Gold, silver, palladium, iridium, antimony, germanium, gallium and the oxides of gallium and germanium may be used for this purpose on the electrode side and germanium, germanium oxide and antimony trioxide or trisulphide on the other. The target may be made by vapour depositing the layers in sequence on the glass face plate, the layer thicknesses being continuously monitored. Grading of the photo-conductive layer is achieved by introducing pellets of a selenium-telluriumarsenic mixture into a heated evaporation boat at a varying rate so that initially each pellet is completely evaporated before the next is introduced. Later, the rate is increased so that the composition of the layer is then determined to any increasing extent by the greater volatility of the selenium. Grading the tellurium content gives the layer as a whole a panchromatic response without sacrificing the high overall dark-resistivity and good resolution characteristic of a selenium layer.
