摘要

A heating-induced monotonous increase in the Yb~(3+) excited state (~2F_(5/2)) lifetimes is found in Yb~(3+) single doped Bi7F_(11)O5 nanocrystals, possibly due to the thermal-enhanced photocarrier separation in polarized layered semiconductors with spontaneous internal electric fields. This unique phenomenon is evaluated for its thermometric performance in terms of lifetime luminescence thermometry, and the maximum absolute/relative temperature sensitivity (S_a/S_r) reaches as high as 0.65 μs K~(-1)/0.24% K~(-1) in biological temperature regions. The results of this work can offer great potential for lifetime luminescence thermometry in biological areas and provide ideas for designing efficient photonic and photoelectric thermal devices.
