In this work, RE³⁺ (Eu, Ce and Sm)‐activated Ca₁₀(PO₄)₆F₂ (fluorapatite) phosphors were synthesized by doping with different apatite minerals (SO₄, VO_4, WO₄) using a solid‐state diffusion method. Optical and structural characterizations were performed using X‐ray diffraction (XRD), Fourier transform infrared spectroscopy, and photoluminescence (PL) spectroscopy. XRD characterization showed the crystalline nature of the phosphor. PL properties were investigated under ultraviolet light excitation for all three rare earths. CIE chromaticity revealed the colour emitted in the visible region. Luminescence intensity was enhanced considerably by tuning the host matrices after core–shell formation by substitution with other ions producing promising candidates for white light‐emitting diode materials.

稀土离子（Eu3 +，Ce3 +和Sm3 +）活化的Ca10（PO4）F2荧光粉通过双重或三重离子化矿物掺杂增强的光致发光：一项比较研究

在这项工作中，通过掺杂不同的磷灰石矿物（SO ₄，VO _4， WO ₄）来合成RE ³⁺（Eu，Ce和Sm）活化的Ca ₁₀（PO ₄）₆ F ₂（氟磷灰石）荧光粉。）使用固态扩散方法。光学和结构表征使用X射线衍射（XRD），傅立叶变换红外光谱和光致发光（PL）光谱进行。XRD表征显示了磷光体的结晶性质。在所有三种稀土的紫外光激发下研究了PL特性。CIE色度揭示了可见区域发出的颜色。通过用其他离子替代形成白色发光二极管材料的有希望的候选物，调整了核-壳形成后的基质，从而显着提高了发光强度。
