| Abstract: | The spectra of photoluminescence (PL), electroluminescence (EL), and optically detected magnetic resonance were studied in ZnS single crystals. It is shown that, in ZnS:Mn crystals, PL at λmax=590 nm excited with light in the extrinsic-absorption region for ZnS (λ = 365 nm) is controlled by the resonance-excitation mechanism; in contrast, the EL can be excited by both the resonance-and impact-related mechanisms. |
