Ho³⁺-Yb³⁺ co-doped transparent glass ceramics containing Sr₃Gd(PO₄)₃ were successfully prepared by the melt crystallization method. The best condition of the thermal treatment was determined to be 780 °C/3 h by differential scanning calorimetry (DSC), X-ray diffraction (XRD) and scanning electron microscope (SEM). The transmittance of glass ceramic was approximately 81% in the visible region. From to the up-conversion emission spectra, the strong green emission (543 nm), weak red (654 nm) and blue emission (483 nm) due to the ⁵F₄/⁵S₂, ⁵F₅, ⁵F₃ → ⁵I₈ transitions of Ho³⁺ can be observed. In addition, the optimum doping concentration of Ho₂O₃ and Yb₂O₃ was 0.3% and 0.8%, respectively. By comparing 0.3%Ho₂O₃-0.8%Yb₂O₃ co-doped with 0.3%Ho₂O₃ doped glass ceramic, the green and red up-conversion luminescence intensity were improved by about 33 times and 21 times, respectively. These results indicated that Ho³⁺-Yb³⁺ co-doped transparent glass ceramic containing Sr₃Gd(PO₄)₃ have potential applications in the field of green up-conversion luminescence.

采用熔融结晶法成功制备了含有Sr ₃ Gd(PO ₄ ) _{3 的}Ho ³⁺ -Yb ³⁺共掺杂透明玻璃陶瓷。通过差示扫描量热法(DSC)、X射线衍射(XRD)和扫描电子显微镜(SEM)确定热处理的最佳条件为780℃/3h。玻璃陶瓷在可见光区的透射率约为 81%。从到上转换发射光谱，由于⁵ F ₄ / ⁵ S ₂、⁵ F ₅、⁵可以观察到Ho ^{3+ 的}F ₃ → ⁵ I ₈跃迁。此外，Ho ₂ O ₃和Yb ₂ O ₃的最佳掺杂浓度分别为0.3%和0.8%。通过比较0.3%Ho ₂ O ₃ -0.8%Yb ₂ O ₃与0.3%Ho ₂ O ₃掺杂的玻璃陶瓷共掺杂，绿色和红色上转换发光强度分别提高了约33倍和21倍。这些结果表明含有Sr的Ho ³⁺ -Yb ³⁺共掺杂透明玻璃陶瓷₃ Gd(PO ₄ ) ₃在绿色上转换发光领域具有潜在的应用前景。
