In this study, it is shown how the temperature range of luminescent thermometers can be widened in an unprecedented way by combining the intra‐ and interconfigurational transitions of the Pr3+ ion in a single material. Using Sr2GeO4:Pr3+ crystalline powders as an illustrative example, the implementation of luminescence thermometry is reported in the broadest temperature range up to now (17–600 K) with a remarkable performance: maximum relative sensitivity values of 9.0% · K−1 (at 22 K, cryogenic range), 0.6% · K−1 (at 300 K, physiological range), and 0.5% · K−1 (at 600 K, high‐temperature range) and minimum temperature uncertainty of 0.1 K.

通过Pr3 +的内部和互构跃迁扩大发光温度计的温度范围

在这项研究中,显示了如何通过将Pr 3+离子在单一材料中的内部和构型转变结合在一起,以前所未有的方式扩展发光温度计的温度范围。以Sr 2 GeO 4:Pr 3+晶体粉末为例,据报道,在迄今为止最宽的温度范围内(17–600 K),实现了发光测温法,具有出色的性能:最大相对灵敏度值为9.0%· K -1(在22 K,低温范围内),0.6%·K -1(在300 K,生理范围内)和0.5%·K -1(在600 K,在高温范围内),最小温度不确定度为0.1 K.
