由于其非常快的短波长发射，掺钕材料作为潜在的闪烁体是当前感兴趣的研究对象。虽然关于掺钕正磷酸盐(晶体形式)及其闪烁性质的最初报道出现在近20年前，但由于对其基本闪烁机理没有深入的了解，它们仍然是一类有趣的材料。在本研究中，我们主要研究了：XPO4：Nd3+，其中X = Y，Lu，La，Sc。研究了在10~350 K不同温度下的脉冲宽度、光吸收、辐射发光和光致发光光谱，并报道了低温和高温热释光测量结果。
Due to their very fast short-wavelength emission, neodymium-doped materials are a subject of current interest as potential scintillators. Although the initial reports regarding neodymium-doped orthophosphates (in crystalline form) and their scintillation properties appeared almost twenty years ago, they remain an interesting class of materials since there is no in-depth understanding of their fundamental scintillation mechanism. In the present research, we focus on the crystalline systems: XPO4:Nd3+, where X = Y, Lu, La, Sc. The pulse height, optical absorption, radioluminescence and photoluminescence spectra were investigated and are reported here for various temperatures from 10 to 350 K. Additionally, results of both low and high temperature thermoluminescence measurements are reported in this communication.
