Abstract:Fluorescent temperature sensors have attracted attention in recent years, due to their potential for use in situations where conventional temperature sensors are unsuitable. There are a lack of appropriate sensors at the microscale for industrial, laboratory, and medical applications. Sm2+:KCl crystals possess luminescence properties that enable them to be used as sensors in a new approach for local temperature measurements, by determining the blueshift or the ratio between the intensities from the allowed 4f–… Show more
“…[8][9][10][11][12] and Sm 2+ . [13][14][15][16][17] The decay lifetime of rare-earth ions can hardly be affected by black body radiation, flame radiation, and sample contamination, which are almost impossible to neglect in many other optical sensing systems. In addition, the effect of thermal quenching on the lifetime measurement is much greater than that on the luminescence intensity.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
