Present technological demands in disparate areas, such as microfluidics and nanofluidics, microelectronics and nanoelectronics, photonics and biomedicine, among others, have reached to a development such that conventional contact thermal probes are not accomplished anymore to perform accurate measurements with submicrometric spatial resolution. The development of novel noncontact thermal probes is, then, mandatory, contributing to an expansionary epoch of luminescence thermometry. Luminescence thermometry based on trivalent lanthanide ions has become very popular since 2010 due to the unique versatility, stability, and narrow emission band profiles of the ions that cover the entire electromagnetic spectrum with relatively high emission quantum yields. Here, a perspective overview on the field is given from the beginnings in the 1950s until the most recent cutting‐edge examples. The current movement toward usage of the technique as a new tool for thermal imaging, early tumor detection, and as a tool for unveiling the properties of the thermometers themselves or of their local neighborhoods is also summarized.

基于镧系元素的温度计：处于发光温度计的前沿

在不同领域中的当前技术需求，例如微流体和纳米流体，微电子学和纳米电子学，光子学和生物医学等，已经达到了一种发展，使得不再能够使用常规的接触式热探针来进行具有亚微米级空间分辨率的精确测量。因此，新型非接触式热探针的开发是必不可少的，这有助于发光测温的扩展时代。自2010年以来，基于三价镧系元素离子的发光测温法已变得非常流行，这是因为该离子具有独特的多功能性，稳定性和窄的发射带分布图，这些离子以相对较高的发射量子产率覆盖了整个电磁光谱。这里，从1950年代开始一直提供该领域的观点概述，直到最近的最前沿例子为止。还总结了该技术作为热成像，早期肿瘤检测的新工具以及揭示温度计本身或附近温度特性的工具的当前趋势。
