Abstract
849,461. Electroluminescence. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 11, 1956 [Oct. 14, 1955], No. 31001/56. Class 39(1). A solid-state image-intensifier, particularly for X-rays, has an electroluminescent layer and a further layer incorporating discrete inclusions of photo-conductive material each extending through the thickness of the further-layer, the further layer also including luminescent material which converts the incident radiation into other radiation more readily absorbed by the photoconductive material, and the two layers being interposed between two electrodes parallel to the two layers. The construction shown in Fig. 1 comprises a glass support 19 coated with a transparent stannic oxide electrode 20, an electroluminescent layer 21, a glass plate 15 pierced with holes 14 coated with photoconductive cadmium sulphide 16 and filled with luminescent calcium tungstate or silveractuated zinc sulphide, and a transparent electrode 17, an A.C. source being connected between the electrodes 17 and 20. The electrode 17 can consist of aluminium deposited from vapour on the face of the glass plate 15. Dimensions are stated. The glass plate 15 can be replaced by one of polystyrene, ethyl-cellulose or ceramic material. Generally the material of the plate 15 has a dielectric constant lower than that of the photo-conductive material 16, and the materials and their proportions can be such that the mean dielectric constant of the whole layer between the electroluminescent layer 21 and the electrode 17 is less than onehalf of that of the photo-conductive material 16. The construction shown in Fig. 3 comprises a glass support 25, a layer of conductive stannic oxide 26, an electroluminescent layer 27, a layer 28 of calcium tungstate formed with a plurality of small apertures filled with photoconductive material 29 such as cadmium sulphide, and a transparent electrode 30. Reference has been directed by the Comptroller to Specifications 763,744 and 765,579.
