摘要	Highly sensitive and precise optical temperature measurements are pivotal across various fields, facilitating enhanced temperature regulation and monitoring. This study achieves an optically ultrahigh sensitivity temperature sensing system in Yb3+/Nd3+/Er3+ tridoped CaSc2O4 by leveraging non-thermal coupling energy levels, specifically Er3+:4F9/2 and Nd3+:4F5/2. This accomplishment circumvents the sensitivity constraint imposed by the energy gap. The maximum absolute and relative sensitivity of the optical thermometer peaks at 13.92% K-1 and 4.61% K-1 respectively, surpassing the values from the majority of analogous optical thermometers. Furthermore, it also exhibits exceptional temperature resolution, maintaining values below 0.03 K throughout the entire testing temperature range. Simultaneously, the temperature sensing properties reliant on the thermally coupled Er3+:2H11/2/4S3/2 states are explored in detail, revealing the maximum absolute and relative sensitivity for temperature measurement of 0.37% K-1 and 1.53% K-1, respectively. In the validation experiment, both of the optical thermometers show accurate temperature measurement capability. Additionally, the penetration depth in the biological tissues is 8 mm for the green and red light of Er3+ and 10 mm for the near-infrared emission of Nd3+. All of these studies collectively demonstrate the potential of CaSc2O4:Yb3+/Nd3+/Er3+ for achieving ultrasensitive temperature sensing and application in the deep biological tissues. Ultrasensitive temperature sensing is realized through non-thermally coupled energy levels to overcome energy gap constraints.
