Abstract
A phosphor and a method of deposition. The phosphor comprises a composition of the formula M'aBa1-aM''2M'''4':RE, where M' is at least one element selected from magnesium and calcium, M'' is at least one element selected from aluminum, gallium and indium, M''' is at least one element selected from sulphur, selenium and tellurium, RE is at least one rare earth element, especially europium or cerium, and 0<a<1. Deposition is preferably by dual source electron beam deposition. The phosphor may be annealed. The phosphor provides a high luminosity blue emission that does not require an optical filter to achieve acceptable colour coordinates for the blue sub-pixel element for a full colour thin film or thick film electroluminescent display. The blue sub-pixel pixel performance meets the luminosity and colour temperature specifications for current generation cathode ray tube displays.
