| Abstract: | Sb3+-doped Sr3(PO4)2 crystals has been synthesized using phosphoric acid, strontium hydroxide and antimony powder as the raw materials through a hydrothermal reaction method. The crystallinity and the microstructure were investigated using X-ray diffraction and scanning electron microscopy. The photoluminescent property was investigated using luminescent spectrometer. Phase pure Sr3(PO4)2 crystal was obtained and it has a shape of hexagonal rod. It showed the emission and excitation peaks at 396, 250, and 215 nm, respectively, indicating that the emission is attributed to 3P1-1S0 transition and the excitation is attributed to 1S0-3P1 and 1S0-1P1 transition. It was also observed that the intensity of photoluminescence is thermally stable up to 673 K. |
