摘要

采用高温固相反应法制备了Er3+和Yb3+共掺杂的LiY(MoO4)2上转换荧光粉。采用均匀设计和二次一般旋转设计相结合的方法计算各因素的最佳掺杂浓度范围，建立Er3+和Yb3+掺杂水平与红绿上转换发射强度的二次回归方程。通过高温固相法制备了优化后的样品，系统地研究了其上转换发光行为，重点研究了温度对上转换发光机理的影响。

Preparation and Up-Conversion Luminescence Properties of LiY(MoO4)2:Er3+/Yb3+ Phosphor through Experimental Optimization Design

Er³⁺ and Yb³⁺ co-doped LiY(MoO₄)₂ up-conversion phosphors were successfully synthesized using the high-temperature solid-state reaction method. A combination of uniform design and quadratic general rotary design was employed to calculate the optimal doping concentration range of each factor, establishing quadratic regression equations correlating the doping levels of Er³⁺ and Yb³⁺ with the red and green up-conversion emission intensities. Optimized samples were prepared through the high-temperature solid-state method, and their up-conversion luminescence behavior was systematically investigated, with particular focus on the effect of temperature on the up-conversion emission mechanism.
