Abstract
Thermal quenching of luminescence materials poses a major obstacle to the technological application of luminescence thermometry. It still remains challenging to attain thermally enhanced light emissions, especially in the second near-infrared window (NIR-II). Herein, an anomalous thermal dependence of NIR-II luminescence in the negative thermal expansion (NTE) Sc2Mo3O12:Er3+/Ho3+ nanocrystals is reported. Mechanistic investigations affirm that Ho3+ ion can work as an energy reservoir and back-transfer to Er3+ ion with the assistance of lattice phonon at elevated temperatures. Moreover, the Ho3+-mediated energy feedback is strengthened by the thermal contraction between dopant ions, thereby enabling a remarkable thermal enhancement of NIR-II emission over 11-fold. The opposite thermal response of Er3+ and Ho3+ emissions is harnessed for NIR-II ratiometric thermometry, registering exceptional performance in a high-temperature regime (Sr = 1.71% K−1, δT = 0.2 K at 513 K). These findings may inspire new insights for addressing the thermal quenching of NIR-II luminescence, which also raises exciting opportunities for flexible thermometry in complex settings.
