Synthesis and Photoluminescence Properties of Eu3+ Doped Strontium Cerium Sulfide Phosphor
T. Niranjan Kumar, Ch. Vijay Anil Dai, K. Suresh
Eu (0.5 mol %) -doped strontium cerium sulfide (SrCeS) phosphor was synthesized by solid state reaction method. The photoluminescent properties of the synthesized phosphor were analyzed by Spectrofluorophotometer. Efficient energy transition has been observed by photoluminescence investigation upon UV visible (263, 320, 466, 535 and 650 nm) excitations and results in red emissions at about 595nm and 611nm. The excitation spectrum monitored under 611nm wavelength consists of broad and sharp peaks covering from 220-650nm. The photoluminescence intensity varies with excitation wavelength. The Commission International de lEclairage (CIE) co-ordinates were calculated by the spectrophotometric method using the spectral energy distribution of 595nm peak is (0.602, 0.397) and of 611nm peak is (0.668, 0.332) confirm the red emission. Chromaticity coordinates does not change distinctly with the change of excitation wavelengths. The phosphor exhibit stable red light indicates that it has potential application in display and in w-LED.
