摘要: 本文采用水热法，以柠檬酸三钠为络合剂，将不同浓度铥离子与氟化锶结合，制备出铥离子掺杂氟化锶纳米光学材料。通过X射线衍射、扫描电子显微镜、荧光光谱和紫外–可见吸收光谱，系统研究了Tm3+掺杂浓度对产物物相、微观形貌及光学性能的影响。物相分析表明样品均为纯相SrF2，形貌受浓度调控。研究发现，随着浓度增加，发光性能先提高再下降，当合成温度为180℃，掺杂稀土铥离子的浓度为0.9 mol%时，其荧光性能与紫外吸收性能达到最大值。
Abstract: In this study, thulium-doped strontium fluoride (SrF2) optical nanomaterials were prepared via a hydrothermal method using trisodium citrate as a chelating agent, with different concentrations of Tm³⁺ ions incorporated into the SrF2 matrix. The effects of Tm3+ doping concentration on the phase composition, morphology, and optical properties were systematically investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence spectroscopy, and UV-vis absorption spectroscopy. Phase analysis indicated that all samples were phase-pure SrF2, and the morphology was found to be concentration-dependent. The results showed that as the doping concentration increased, the luminescence performance first improved and then decreased. The optimal fluorescence and UV absorption properties were achieved when the synthesis temperature was 180˚C and the Tm³⁺ doping concentration was 0.9 mol%.
