摘要

采用高温固相反应法制备了新型荧光粉Ca2Mg(BO3)2: Ce3+。采用粉末x射线衍射(XRD)对相纯度进行了表征。研究了Ce3+的紫外-可见(UV-Vis)光学性质，确定了Ce3+在主晶格中的最低5d能级、发射和Stokes位移。此外，还对其浓淬过程进行了研究。结果表明，Ce3+离子在UV-Vis范围内进入Ca2+位点只有一次发射，最佳掺杂浓度为x = 0.05。对激发光谱和发射光谱进行了评估，清晰地揭示了发光特征。

The Ultraviolet-Visible Luminescence of Ce3+ in Ca2Mg(BO3)2 Phosphors with Potential Applications

New phosphors Ca2Mg(BO3)2: Ce3+ were synthesized by the solid-state reaction method at a high temperature. The phase purity was characterized by powder X-ray diffraction (XRD). The ultraviolet-visible (UV-Vis) optical properties of Ce3+ have been investigated, and the lowest 5d levels, the emission, and the Stokes shifts of Ce3+ in the host lattice were identified. In addition, its concentration quenching process was also studied. The results show that Ce3+ ions enter Ca2+ sites with only one emission in a UV-Vis range and that the optimum doping concentration is x = 0.05. The excitation and emission spectra were evaluated to clearly reveal luminescence features.
