Pr3+-doped perovskite niobate ceramics towards improving performance of optical temperature sensor by second harmonic generation (SHG) combined with lanthanide luminescence
Abstract
(KxNa1-x) NbO3 (KNN) perovskite ceramics doped with Pr3+ ions were successfully synthesized. Under pulsed laser excitation, the KNN: Pr3+ material shows intense Pr3+ down-shifting luminescence combined with color-tunable, excitation wavelength-dependent second-harmonic generation (SHG) phenomena. The intensity ratio between the Pr3+ emission bands, as well as between the Pr3+ and the SHG signal were analyzed as a function of temperature. The intensity ratio from Pr3+ emission bands of I610/I655 has a maximum relative sensitivity of 6.41 %K−1 at 420 K. In the case of the ISHG/I610 ratio, the maximum sensitivity of 5.93 %K−1 at 560 K was obtained. Temperature resolutions were also analyzed, with the ISHG/I610 ratio showing minimum values of 0.07 K compared to the minimum of 0.105 obtained for the I610/I655 ratio. Worth mentioning that the use of SHG allows to increase the working range of the thermal sensor more than 140 K, as the ratio between Pr3+ emission bands could not be measured further than 420 K due to the thermal quenching effect of the 3P0 → 3F2 transition. The developed thermometer can be used as a highly-sensitive, dual-mode (multi-parameter) temperature sensor, i.e., combining luminescence thermometry and SHG based thermometry.
