Abstract:
Owing to the impact of robust thermal quenching, lanthanide-based luminescence thermometer operation can usually only be achieved within a comparatively small temperature scope (ambient temperature to 800 K). Here, this study presents a method for addressing the mentioned limits, and a luminescence thermometer with an ultra-wide temperature range has been achieved, which adopted Pr 3+ -doped Ba(Zr 0.16 Mg 0.28 Ta 0.56 )O 3 transparent ceramic to be the optical temperature probe. Based on the high luminescence intensity and excellent thermal stability of the 3 P 0 – 3 F 2 hypersensitive transition of Pr 3+ in Ba(Zr 0.16 Mg 0.28 Ta 0.56 )O 3 transparent ceramic, the intensity ratio of the emissions at 624 nm and 649 nm was employed for temperature sensing in an ultra-wide range (293–873 K), and the maximal relative sensitivity reached 1.05% K −1 , outperforming most existing luminescence temperature measurement transparent ceramics. Furthermore, in Pr 3+ -doped Ba(Zr 0.16 Mg 0.28 Ta 0.56 )O 3 transparent ceramic, the lifetime of the 3 P 0 – 3 H 4 transition also exhibits prominent optical thermometry performance (303–873 K). The results presented in this work may be of high significance for the design of novel ratiometric/lifetime dual-mode optical temperature sensors in the high-temperature measurement field.
