摘要

Abstract

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.
