We report that non-contact self-referencing temperature sensors can be realized with the use of core-shell nanostructures. These lanthanide-based nanothermometers (NaGdF4:Yb(3+)/Tm(3+)@Tb(3+)/Eu(3+)) exhibit higher sensitivity in a wide range from 125 to 300 K based on two emissions of Tb(3+) at 545 nm and Eu(3+) at 615 nm under near-infrared laser excitation.
我们报告称，利用核壳纳米结构可以实现非接触式自基准温度传感器。这些基于镧系元素的纳米温度计（NaGdF4:Yb(3+)/Tm(3+)@Tb(3+)/Eu(3+)）在近红外激光激发下，基于 Tb(3+)在 545nm 和 Eu(3+)在 615nm 的两个发射，在 125 至 300K 的宽范围内表现出更高的灵敏度。
