Tm) phosphors were synthesized by the conventional solid-state reaction at 950℃ for 2 h. The samples were characterized by X-ray diffraction (XRD) and photoluminescence (PL) spectra. The experimental results indicate that all the obtained-samples are pure hexagonal phase. Under UV light excitation

the doped rare earth ions (Tb
