Spectroscopic and structural studies of Sm2+ doped orthophosphate KSrPO4 crystal
View through CrossRef
Sm 2 + ions doped KSrPO4 were prepared by high-temperature solid-state reaction method. The samples were investigated by x-ray powder diffraction, photoluminescence excitation and emission spectra, and luminescence decay measurements. After excitation into the 4f55d1 levels, the emission of Sm2+ ions showed D05→FJ7 (J=0,1,2) emission together with the broad 5d→4f emission band. The luminescence of Sm2+ ions was sensitive to the temperature. With the decreasing of the temperature, the broad 5d→4f emission band of Sm2+ ions gradually quenched, while D05→FJ7 (J=0,1,2) emission lines could be clearly detectable. Based on the luminescence properties of Sm2+ ions and structure of KSrPO4 crystal, the crystallographic sites and the energy structure correlated with 4f→5d transitions of Sm2+ ions in KSrPO4 were discussed.
