Heating-induced abnormal increase in Yb3+ excited state lifetime and its potential application in lifetime luminescence nanothermometry

Author affiliations

Abstract

The heating-induced unprecedented monotonous increase in Yb3+ excited state (2F5/2) lifetime is found in Nd3+/Yb3+ codoped fluoride nanoparticles, which is proved to originate from the alleviation of energy migration-mediated surface quenching with elevated temperature. This unique phenomenon is evaluated for thermometric performance in terms of lifetime luminescence thermometry, and the maximum absolute/relative temperature sensitivity (Sa/Sr) reaches as high as 2.68 μs K−1/1.59% K−1 in the biological temperature region, indicating that the studied nanomaterial can offer great potential for lifetime luminescence thermometry in biological areas.
