Upconversion luminescence and optical temperature sensing properties of Yb/Er/Li tri-doped ZnMoO phosphors were investigated. It has been demonstrated that Li doping affected not only the local symmetry of Yb and Er but also the distribution of them in the host lattice. As a result, the significantly improved green upconversion luminescence was obtained when excited at 980 nm. The pumping power dependent photo-thermal behavior was used to evaluate the reliability of upconversion temperature sensing. An accurate temperature scale was established by eliminating the impact of thermal effect, and the sensing ability was evaluated via a comparison with the results reported in literatures.
研究了 Yb/Er/Li 三掺杂 ZnMoO 荧光粉的上转换发光和光学温度传感性能。研究表明，Li 掺杂不仅影响 Yb 和 Er 的局域对称性，而且影响它们在宿主晶格中的分布。结果，在 980nm 激发时获得了显著增强的绿光上转换发光。利用泵浦功率相关的光热行为来评估上转换温度传感的可靠性。通过消除热效应的影响建立了准确的温度标度，并通过与文献报道的结果进行比较来评估传感能力。
