摘要

探测极端温度在冶金、航空航天、核工业甚至天文学领域都发挥着关键作用。在这方面，能够探测 3000 K 以上温度的材料和光学技术仍处于起步阶段。在此，我们报告了通过黑体发射对 3800 至 4500 K 温度的探测，为此我们使用了金属有机框架（MOFs）。激光辐射对 MOFs 的快速加热会导致阈值黑体发射（中心波长为 650 至 750 nm），其相应的温度与 MOF 的结构直接相关。有关 MOFs 黑体发射温度与结构相关的研究结果，拓展了 MOFs 在光子学和传感领域的应用。

Detection of extreme temperatures via emission from MOFs of a varied structure

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.

期刊介绍： This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
