Abstract
We investigated the structure and photoluminescence properties of novel Ba2âxSi4O10:2xSm3+ phosphor prepared by the solid state reaction method. In the prepared phosphor the high temperature monoclinic phase was dominant over the low temperature orthorhombic phase. The shifting of the X-ray diffraction peaks with the Sm3+ ion addition was explained on the basis of the refinement results. The photoluminescence study showed that on excitation with 402Â nm the phosphor emitted at 560Â nm, 600Â nm and 645Â nm which corresponds to the 4G5/2â4H5/2, 4G5/2â4H7/2 and 4G5/2â4H9/2 transitions, respectively. Concentration quenching effect was also observed in the prepared phosphor. CIE chromaticity coordinates showed that the phosphor can be further developed for display applications.
