Abstract
The results of luminescence, absorption and XRD studies of some (ZnS : 1% w t CaS) and (CaS : 1% wt ZnS) phosphors when doped with impurities like Cu, Sm/Pr and Cl have been presented. Emission peaks at 420 nm (due to Cu), 480 nm (due to Zn) and in the region 730-740 nm (due to Sm Sm/Pr) have been fo und. Absorption spectra consists of a number of peaks due to native lattice alongwith the presence of different ingredients used. ZnS based systems ha ve been found to be more susceptible to oxidation.
