Electroluminescent characteristics and the photodepolarization spectra of ZnS:Mn thin-film electroluminescent devices made with two different atomic-layer epitaxy processes based on chlorine and metalorganic precursors have been studied during initial stage of accelerated aging. Essential differences have been revealed. They are explained in assumption that different impurity centers exist in the ZnS:Mn films grown by using chlorine and metalorganic precursors, namely, MnCl₂, Cli⁻, Cls⁺ and isovalent oxygen traps, respectively. The mechanism of aging in both types of devices is discussed.
