Abstract

In this study, color-tunable nanocrystalline phosphors of ZnS: 0.5 mol % Mn ₂+ (SZn ratio = 1, 0.85, 0.75, 0.65, 0.5) were synthesized at a low temperature using the solid-state reaction method. The emission spectra of ZnS: 0.5 mol % Mn ₂+ samples excited at 325 nm exhibited two emission peaks. The blue-light emission is due to the donor-acceptor recombination in the ZnS host, and the orange-light emission is attributed to the T14 → A16 transition of Mn ₂+ ions. The chromaticity coordinates of the phosphors changed from orange, near white, to blue with decreasing SZn ratio. The local strain and the quantum efficiency of the ZnS: Mn ₂+ phosphors are also investigated.
