Detection of extreme temperatures plays a key role in metallurgy, aerospace, nuclear industries, and even astronomy. Herein, materials and optical technologies capable of detecting the temperatures above 3000 K are still in their infancy. Here, we report on a detection of 3800 to 4500 K through the emission of a blackbody, for which the metal-organic frameworks (MOFs) are used. The rapid heating of MOFs by laser radiation leads to the threshold blackbody emission (centered from 650 to 750 nm), the corresponding temperature of which is directly related to the structure of MOF. The results on such structure-related temperatures of the blackbody emission of MOFs, thereby, expand their use in photonics and sensing in general.

通过不同结构的 MOF 的发射来检测极端温度

极端温度的探测在冶金、航空航天、核工业甚至天文学中发挥着关键作用。其中，能够检测3000 K以上温度的材料和光学技术仍处于起步阶段。在这里，我们报告了通过使用金属有机框架 (MOF) 的黑体发射检测 3800 至 4500 K。激光辐射对MOF的快速加热导致黑体发射阈值（以650至750 nm为中心），其相应的温度与MOF的结构直接相关。MOF 黑体发射的这种与结构相关的温度结果，从而扩大了它们在光子学和传感领域的应用。
