Structural and Optical Properties of Samarium Doped Sr2CeO4 via Solid State Reaction Method


Strontium cerium oxide Sr2CeO4 doped Sm3+ phosphor was synthesized by solid state reaction method at temperature 12000 C for 4h. The powder samples were characterized by X-ray diffraction (XRD), Raman spectra, Fourier Transform infrared spectra (FTIR), Scanning Electron microscope (ESM), Energy dispersive spectra (EDS), and photoluminescence. The X-Ray diffraction pattern reveals the crystallite size and the structure is orthorhombic. Photoluminescence excitation and emission spectra of Sr2Ce O4: xSm3+ (0.5 ≤ x ≤1.5) are recorded at room temperature. The color co-ordinates for the Sr2Ce O4: 1.0 mol % Sm3+ were x =0 .6687 and y = 0.3311.This phosphor has a good potential for applications in display devices.
