摘要
High-performing lanthanide (Ln3+)-based luminescence thermometry is gaining widespread attention for its remote temperature reading, broad temperature range, high sensitivity, resolution, and stability in various applications. However, facile strategies for constructing multi-mode luminescence thermometry based on a simple material system are still challenging. Herein, we propose a dual-mode single-band ratiometric (SBR) luminescence thermometry based on the tunable Eu3+ luminescence in La2(WO4)3 (LaWO). Eu3+-doped La2(WO4)3 (LaWO:Eu) phosphor was synthesized by the high-temperature solid-state method. The rigid lattice of LaWO allows high content of Eu3+ doping without concentration quenching of luminescence, which endows high fluorescence intensity. In addition, in-situ and dynamic regulations of thermal-responsive luminescent properties of Eu3+ are systematically investigated, which enables the construction of SBR luminescence thermometry. At temperatures from 300 to 500 K, the maximum absolute and relative sensitivities reach 0.032 K-1 and 0.85% K−1, respectively. The high sensitivity and stability indicate that our results provide a facile and effective strategy for developing multi-mode luminescence thermometry and hold potential applications in various fields.
