In this paper, possibilities and limits of the application of REE3+ luminescence (especially the Nd3+4F3/2 → 4I9/2 emission) as structural probe are evaluated. Important factors controlling the Nd3+ luminescence signal are discussed, including effects of the crystal-field, crystal orientation, structural state, and temperature. Particular attention was paid to the study of the accessory minerals zircon (ZrSiO4), xenotime–(Y) (YPO4), monazite–(Ce) (CePO4) and their synthetic analogues. Based on these examples we review in short that (1) REE3+ luminescence can be used as non-destructive phase identification method, (2) the intensities of certain luminescence bands are strongly influenced by crystal orientation effects, and (3) increased widths of REE3+-related emission bands are a strong indicator for structural disorder. We discuss the potential of luminescence spectroscopy, complementary to Raman spectroscopy, for the quantitative estimation of chemical (and potentially also radiation-induced) disorder. For the latter, emissions of Nd3+-related centres are found to be promising candidates.

影响矿物Nd3+(REE3+)发光的因素

本文评估了REE3+发光（尤其是Nd3+4F3/2→4I9/2发射）作为结构探针的应用可能性和局限性。讨论了控制 Nd3 + 发光信号的重要因素，包括晶体场、晶体取向、结构状态和温度的影响。对副矿物锆石（ZrSiO4）、磷钇矿-（Y）（YPO4）、独居石-（Ce）（CePO4）及其合成类似物的研究受到了特别关注。基于这些例子，我们简要回顾一下：(1) REE3 + 发光可作为非破坏性的物相识别方法，(2) 某些发光带的强度受晶体取向效应的强烈影响，以及 (3) 增加的宽度REE3 + 相关的发射带是结构无序的有力指标。我们讨论了与拉曼光谱互补的发光光谱的潜力，用于定量估计化学（也可能是辐射诱导的）无序。对于后者，发现 Nd3 + 相关中心的排放是有希望的候选者。
