报道了一种独特的Eu 3 +/Tb 3+发光自参考纳米温度计，允许在10-350 K温度范围内进行绝对测量，并具有亚微米空间分辨率（见图）。它具有高达4.9%·K−1的温度灵敏度和长期使用的高光稳定性。分子测温，超顺磁性和发光在纳米主体矩阵的组合提供了多功能性开辟了新的令人兴奋的应用。
A unique Eu3+/Tb3+ luminescent self-referencing nanothermometer allowing absolute measurements in the 10–350 K temperature range and sub-micrometer spatial resolution is reported (see Figure). It has up to 4.9%·K−1 temperature sensitivity and high photostability for long-term use. The combination of molecular thermometry, superparamagnetism and luminescence in a nanometric host matrix provides multifunctionality opening the way for new exciting applications.
