Abstract:To develop multi‐mode fluorescence thermometer with high performance, Lu2WO6:Er3+,Yb3+ materials were successfully designed and prepared. Under 980 nm excitation, the material can achieve accurate temperature measurement under three models. The above three models are based on different parameters, including two FIR (fluorescence intensity ratio) derived from two thermally coupled energy levels (TCELs) (2H11/2/4S3/2) and two non‐thermally coupled energy levels (NTCELs) (2H11/2/4F9/2), as well as fluorescence li… Show more
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.
