Abstract

Luminescence intensity ratio (LIR) thermometry is of great interest, because of its wide applications of noninvasive temperature sensing. Here, a LIR thermometry based on combined ground and excited states absorptions is developed using CaWO₄:Tb³⁺. The ratio of single luminescence (⁵D₄-⁷F₅) intensities under 379 and 413 nm excitations with opposite temperature dependences, attributed to the thermal coupling of ground state ⁷F₆ and excited state ⁷F₅, is used to measure temperature. This LIR method achieves a high relative sensitivity of 2.8% K⁻¹, and can avoid complex spectral splitting by collecting all down-shifting luminescence bands, being a promising accurate luminescence thermometry.
