It has been an open question whether Nd3+ ions are incorporated into the crystalline phase in oxyfluoride glass ceramics or not. Moreover, relative research has indicated that spectra characters display minor differences between before and after heat treatment in oxyfluoride glass compared to similar Er3+-, Yb3+-, Tm3+-, Eu3+-, etc.-doped materials. Here, we have studied the distribution of Nd3+ ions in oxyfluoride glass ceramics by X-ray diffraction quantitative analysis and found that almost none of the Nd3+ ions can be incorporated into the crystalline phase. In order to confirm the rationality of the process, the conventional mathematical calculation and energy-dispersive spectrometry line scanning are employed, which show good consistency. The distribution of Nd3+ ions in oxyfluoride glass ceramics reported here is significant for further optical investigations and applications of rare-earth doped oxyfluoride glass ceramics.
钕离子（Nd3+）是否会掺入氟氧化物微晶玻璃的晶相一直是个悬而未决的问题。此外，相关研究表明，与类似的掺铒（Er3+）、镱（Yb3+）、铥（Tm3+）、铕（Eu3+）等材料相比，氟氧化物玻璃在热处理前后的光谱特征显示出微小差异。在此，我们通过X射线衍射定量分析研究了氟氧化物微晶玻璃中Nd3+离子的分布，发现几乎没有Nd3+离子能够掺入晶相。为了证实该过程的合理性，采用了传统的数学计算和能谱线扫描，结果显示出良好的一致性。本文报道的氟氧化物微晶玻璃中Nd3+离子的分布对于稀土掺杂氟氧化物微晶玻璃的进一步光学研究和应用具有重要意义。
