Ortho-phosphates according to the composition ABPO₄ (A = Li⁺, Na⁺, and K⁺; B = Mg²⁺, Ca²⁺, Sr²⁺, and Ba²⁺) are often investigated and used as hosts for Pr³⁺ activated phosphors or scintillators. In this work, the characterisation as well as the synthesis of microcrystalline Na_1+xCa_1-2xPO₄:Pr³⁺_x is discussed. In order to ensure that the investigated samples are single phase compounds, X-ray powder diffraction measurements were performed. The material was studied regarding its suitability as a UV-C emitting phosphor. Furthermore, the emission spectrum in the visible range was evaluated. Spectroscopic examinations included the temperature-dependent determination of the excitation and emission spectra as well as the measurement of the diffuse reflection characteristics. In order to evaluate its suitability as scintillator material, the emission of the samples was measured upon X-ray irradiation.

根据组成AB PO _{4 的}正磷酸盐（A  = Li ⁺、Na ⁺和 K ⁺；B = Mg ²⁺、Ca ²⁺、Sr ²⁺和 Ba ²⁺）经常被研究并用作宿主Pr ³⁺激活的磷光体或闪烁体。在这项工作中，微晶Na _1+x Ca _1-2x PO ₄ :Pr ³⁺ _x的表征和合成进行了讨论。为了确保所研究的样品是单相化合物，进行了 X 射线粉末衍射测量。研究了该材料作为 UV-C 发射荧光粉的适用性。此外，评估了可见光范围内的发射光谱。光谱检查包括激发和发射光谱的温度相关测定以及漫反射特性的测量。为了评估其作为闪烁体材料的适用性，在 X 射线照射下测量样品的发射。
