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 4T1→6A1 transition. The emission spectra shows single peak having sharp shape and strong intensity at 535 nm. It can be used as a green phosphor.
