Synthesis and luminescence properties of novel NaSCN: xCe3+ phosphor

Abstract

The blue-emitting novel phosphor NaSCN: xCe3+(x = 0.005,0.01,0.02) is reported here for the first time. The synthesis method is simple, time saving, and cost effective. X-ray power diffraction (XRD) analysis confirmed the formation of said phosphor, and SEM images were recorded for the surface morphology. Photoluminescence emission (PL) and excitation (PLE) measurements were also recorded. Variations in emission intensity with the Ce3+concentration were observed and recorded leading to determination of the critical concentration. The concentration quenching observed in this phosphor is due to mainly electric multipole interaction. The CIE1931 color co-ordinates and the critical distance were determined.
