| Abstract | The present paper reports synthesis and photoluminescence characteristics of Eu 3+ (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mol %) doped red-emitting nano phosphors of Sr2Y2CeO7. The phosphor were prepared using standard solid state diffusion reaction technique without and with citric acid as flux. The formation of single phase compound was verified through X-ray diffraction (XRD) studies. The photoluminescence excitation and emission spectra were investigated. The phosphor can be efficiently excited by 254nm to realize an intense and very narrow luminescence lines 582 and 595 nm corresponding to the magnetic dipole transition 5 D0→ 7 F1 and 613, 625nm corresponding to the electric dipole transition 5 D0→ 7 F2 of Eu 3+ ions. The phosphor may find a potential application in the display and CFL lamps as one of the phosphor component for white light generation. |
