| Popis: | We report here, the Ca9La(PO4)5(SiO4)F2:1 mol%Eu3+ phosphor via doping of chloride, molybdate, vanadate, sulfate, and tungstate ions that were synthesized by high-temperature solid-state reaction method. The phase formation was confirmed by X-ray diffraction (XRD) measurements. Morphological studies were performed using scanning electron microscopy. Photoluminescence and thermoluminescence properties of the synthesized phosphors were systematically studied. The PL excitation spectra of host material show peaks at 395 nm and 466 nm corresponding to 7F0 → 5L6 and 7F0 → 5D2 transitions of Eu3+, respectively. Further photoluminescence properties also studied after doping of molybdate, vanadate, sulfate, and tungstate ions in host material. When excited at 395 nm and 466 nm, PL emission spectra show emission band at around 595 nm and 616 nm, which attributes to 5D0 → 7F1 and 5D0 → 7F2 transitions, respectively. Further TL glow curves of all the synthesized phosphors were studied when exposed to γ-rays. |
