Abstract

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.
