Abstract A study was made of electroluminescence in ZnO-ZnSe: Cu, Cl type luminophors as a function of band-gap of the resultant host lattice. By altering relative proportions of the oxide and the selenide, a number of samples were prepared, giving electroluminescent emission covering a wide spectral range from green to red. The emission spectrum shifts toward the red due to successive reduction of band gap of the combined system as the percentage amount of ZnSe is increased. The effect of firing atmosphere in the preparation of these luminophors is also described. Taking (0.5 ZnO, 0.5 ZnSe): Cu, Cl as a specific sample, different emission bands were recorded when excited by A.C. field and the ultraviolett radiations. The electroluminescent brightness of the sample follows the relationB=B 0 e−b/√¯v at normal frequencies and voltages.
