Abstract
815,422. Luminescence, electroluminescence. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 2, 1957 [Sept. 5, 1956], No. 27596/57. Class 39(1). A solid state image intensifier comprises a luminescent layer 3 having an electrode 2 and a photosensitive layer 8 extending over a reliefed substratum of insulating material showing a relief of alternate raised and hollow portions 5, 6 and lying between the layers 3, 8 the hollow portion 6 extending through the substratum towards the luminescent layer 3 and the electrodes 7 for the photosensitive layer 8 being provided on the tops of the raised portions 5. As shown the insulating substratum 5, 6 is formed of fine-grained powdered glass or of polystyrene in a binder of urea formaldehyde and is provided with a plurality of parallel V- shaped grooves. In a second embodiment the substratum is constituted by the insulating envelope of a plurality of parallel thin metal wires having a diameter less than that of its insulating envelope, the thickness of which on the side of the layer 3 is less than half that of the thickness on the other side. The insulating envelope is preferably aluminium oxide deposited by cataphoresis. In another embodiment the substratum is constituted by a plurality of glass beads closely packed in a plane parallel to the layer 3, the halves of the beads adjacent this layer being embedded in a feebly conductive layer capable of diffusing the electric current. In Fig. 1 the luminescent layer 3 and the substratum 5, 6 are separated in the region of the hollow portion 6 by individual auxiliary electrode elements 4 the space between which may be black-lacquered to prevent optical feedback. Alternatively the material of the substratum may be opaque to prevent feedback. A thin reflecting insulating layer of titanium dioxide or magnesium oxide may be located between layer 3 and electrodes 4. The electrodes strips 7 may be located above the layer 8 and may be formed by metal strips on a transparent foil. The photosensitive layer may be of cadmium sulphide activated by copper and chlorine and the luminescent layer, 50 microns thick, may be of zinc sulphide activated by copper and aluminium in a binder of urea formaldehyde. Instead of this electroluminescent material the layer 3 may be of a phosphor whose luminescence is extinquished in the presence of an electric field e.g. of zinc sulphide activated by cadmium and gallium. In this case the layer 3 is flooded by a suitable auxiliary radiation and the luminescence is locally extinquished according to the pattern of the incident radiation.
