Abstract

<PICT:1022725/C4-C5/1> An electroluminescent device comprises a body of electroluminescent material 1, spaced from an electrode structure 7 by an insulating layer 3 thin enough to permit tunnelling, and carrying on its opposite surface a rectifying contact 5, an alternating voltage of at least 1 volt being applied across the device. The electroluminescent material has a resistivity of about 10 ohm. cm., and may be a single crystal of cadmium sulphide, cadmium telluride, cadmium selenide or zinc telluride. The insulating layer may be a film of aluminium oxide, 50 <\>rA thick, or a film of cellulose nitrate or polyvinyl formal, 100 <\>rA thick. The electrode 7 and contacts 5, 9 may be of gold, copper, platinum, silver or aluminum. The continuous electrode layer 7 may be replaced by metallic particles supported by the insulating layer 3 which acts as a binder therefor.
