摘要	Design and fabrication of contactless optical thermometer with rapid and accurate performance has become a research hotspot in recent years. Herein, CaSc2O4:Yb3+/Er3+ is employed as the intermediary for temperature sensing under the excitation of 980nm, which is proven to afford an ultra-sensitive and high-resolution optical thermometry in multiple ways based on the fluorescence intensity ratio (FIR) technology. The optimal thermal sensing behaviors are realized by the FIR of Er3+:2H11/24I15/2 to 4S3/24I15/2 transition, which has a relative sensitivity of 1184/T2 and a minimal resolution of 0.03K along with a maximal absolute error of 0.96K. Besides that, the FIR between the thermally coupled Stark sublevels of Er3+:4F9/2 manifold (FIRR) as well as that of Er3+:4I13/2 manifold (FIRN) can also provide excellent optical thermometry. The relative sensitivity of FIRR-based and FIRN-based optical thermometers are calculated to be 402/T2 and 366/T2, respectively, with a same minimal resolution of 0.09K, which possess the potential to be used for biomedicine due to the inherent advantage of their operating wavelengths located in the biological window. The results demonstrate that CaSc2O4: Yb3+/Er3+ is a promising candidate for temperature sensing with multipath, high sensitivity, and superior resolution. 2021 The American Ceramic Society
