Abstract
843,274. Electroluminescence. GENERAL ELECTRIC CO. June 17, 1957 [June 19, 1956], No. 18989/57. Class 39(1). A vibration to radiation transducer enabling the detection, observation, or measurement of stress patterns comprises a layer 10 of piezoelectric material, a layer 16 of electroluminescent phosphor, these layers being in contact with each other at a common interface and electrodes 17, 18 in contact with these layers at points remote from the interface, the electrode 18 in contact with the phosphor being at least in part transparent and the electrodes being connected together by a conductor 21. As shown the device is utilisedto indicate vibrations in a body 22 but may be used to analyse the stress patterns in the piezoelectric layer itself by vibrating this electrically. For detecting weak vibrations an intensifier comprising a photoconductive, electroluminescent combination may be added to the device. In such a case the phosphor 16 is preferably gallium phosphide emitting red light and the photoconductive layer is cadmium selenide responsive thereto, while the electroluminescent phosphor in the intensifier is green-emitting copper activated zinc sulphide.
