Abstract
Polycrystalline CaS:Ce3+ and SrS:Ce3+ phosphors were successfully synthesized via the carbo-thermal reduction method. The XRD patterns of prepared phosphors were well matched with ICDD files and surface morphology of prepared phosphors were found to be in sub micron range. Photoluminescence emission spectra of CaS:Ce3+ and SrS:Ce3+ exhibits green and blue broad band emissions centered at 504nm and 477nm respectively. The concentration quenching phenomena was observed for prepared phosphors. CIE coordinates of Ce3+ doped CaS and SrS phosphors were calculated. The critical transfer distance (Rc) is calculated by equation proposed by Blasse. Thus prepared phosphors are suitable for pc-WLED.
