Abstract

YAlO3: Sm3+ phosphor has been synthesized by the solid state reaction method with calcium flouride used as a flux. The resulting YAlO3: Sm3+ phosphor was characterized by X-ray diffraction (XRD) technique, Fourier transmission infrared spectroscopy (FTIR), photoluminescence . . PL excitation spectrum was found at 254,332,380,400,407, 603 and 713 nm. Under excitation of UV(713 nm) YAlO3: Sm3+ (0-3 %) broad band emission were observed from 400 to 790 nm with a maximum around 713 nm of YAlO3 host lattice accompanied by weak emission of Sm3+ ((4)G(5/2) - (H5/2,H7/2)-H-6-H-6,H-6(9/2)) transitions. The results of the XRD show that obtained YAlO3: Sm3+ phosphor has a orthorhombic structure. The study suggested that Sm3+ doped phosphors are potential luminescence material for laser diode pumping and inorganic scintillators.
