Absolute temperature sensitivity (Sa) reflects the precision of sensors that belong to the same mechanism, whereas relative temperature sensitivity (Sr) is used to compare sensors from different mechanisms. For the fluorescence intensity ratio (FIR) thermometry based on two thermally coupled energy levels of one rare earth (RE) ion, we define a new ratio as the temperature-sensing parameter that can vary greatly with temperature in some circumstances, which can obtain higher Sa without changing Sr. Further discussion is made on the conditions under which these two forms of temperature-sensing parameters can be used to achieve higher Sa for biomedical temperature sensing. Based on the new ratio as the temperature-sensing parameter, the Sa and Sr of the BaTiO3: 0.01%Pr3+, 8%Yb3+ nanoparticles at 313 K reach as high as 0.1380 K–1 and 1.23% K–1, respectively. Similarly, the Sa and Sr of the BaTiO3: 1%Er3+, 3%Yb3+ nanoparticles at 313 K are as high as 0.0413 K–1 and 1.05% K–1, respectively. By flexibly choosing the two ratios as the temperature-sensing parameter, higher Sa can be obtained at the target temperature, which means higher precision for the FIR thermometers.

基于热耦合理论的荧光强度比测温的两种形式的温度传感参数研究
绝对温度灵敏度（S a）反映属于同一机构的传感器的精度，而相对温度灵敏度（S r）用于比较来自不同机构的传感器。对于基于一个稀土（RE）离子的两个热耦合能级的荧光强度比（FIR）测温法，我们定义了一个新的比值作为温度感测参数，该参数在某些情况下会随温度变化很大，从而可以获得更高的S a不更改S r。在这两种形式的温度感应参数可用于获得更高S a的条件下进行了进一步的讨论用于生物医学温度感测。根据新的比率作为温度传感参数，BaTiO 3的S a和S r：在313 K时0.01％Pr 3+，8％Yb 3+纳米粒子分别达到0.1380 K –1和1.23％K分别为–1。同样，BaTiO 3的S a和S r：313 K时1％Er 3+，3％Yb 3+纳米粒子分别高达0.0413 K –1和1.05％K –1， 分别。通过灵活选择这两个比率作为温度传感参数，可以在目标温度下获得更高的S a，这意味着FIR温度计的精度更高。
