ABSTRACT OF THE DISCLOSURE Electroluminescent panels and method of manufacture. A method in which a phosphor film of manganese doped zinc chalcogenide is produced by chemical vapour deposition from alkyl zinc vapour and the gaseous hydride of the chalcogen. The manganese dopant is intro- duced uniformly during deposition by decomposition of tricarbonyl alkylcyclopentadienyl manganese:- Image where here R denotes the alkyl radical. Preferably dimethyl zinc and tricarbonyl methlcyclopentadienyl manganese are used. The phosphor produced may be one of the following manganese doped compounds: zinc sulphide, zinc selenide, zinc sulphul selenide, zinc oxy-sulphide, zinc oxy-selenide or zinc cadmium su1phide.
