Abstract
In the work, photoluminescence (PL) and thermoluminescence (TL) spectra of a zinc sulfide phosphor series, namely microcrystalline ZnS:Cu obtained by self-propagating high-temperature synthesis (SHS), were obtained and analyzed. Based on the spectral analysis, the character of the influence of annealing parameters on the intensity of the “blue” (B) and “green” (G) PL bands is established. The behaviors of the PL and TL bands are compared and the TL bands in the blue and green spectral regions are identified. The TL mechanism was assumed to be the specific nature of the centers that cause the B- and G-bands of PL.
