Abstract

CeSOCl: Mn phosphor is prepared by wet chemical method. The spectroscopic study and electronic states of Mn2+ are derived from excitation spectra for greenemitting CeSOCl: Mn phosphor and is found to give a spectrum consistent with linear symmetry in increasing intensity of Mn2+ ion. Mn2+ emission at 535 nm was observed in the present host due to 4T16A1 transition. The emission spectra shows single peak having sharp shape and strong intensity at 535 nm. It can be used as a green phosphor.
