Abstract

The structural and optical properties on $Tb^{3+}$ addition into LiGd$(PO_3)_4$ compound were investigated by X-ray powder diffraction and photoluminescence spectroscopy. The emission spectrum shows the strongest peak corresponding to the $^5D_4{\rightarrow}^7F_5$ transition of $Tb^{3+}$ at 546 nm under 147 nm and 173 nm excitation. 85 mol% concentration of $Tb^{3+}$ for LiGd$(PO_3)_4$ is much higher than other Tb-doped phosphors.
