“…On the other hand, the perovskite-type oxides have excellent physical properties, chemical stability, and low lattice phonon energies, which are considered to be one of the most promising UC hosts for various applications [18,21,22] . Till now, extensive research activities have been devoted to the rational design and synthesis of UCL materials by employing perovskite oxides as host materials [17,[23][24][25] . For example, owing to the difference in the symmetry of the crystalline structure, the phase transition and the A/B site of Er-doped perovskite BaTiO 3 will significantly affect the UCL intensity [17] .…”

“…As a result of the excellent UCL properties, perovskite-type oxides are also used as temperature sensor materials. Such temperature sensing is a noncontact measurement with high sensitivity, high signal discriminability, and broad range dynamic imaging [16,24,26,27] . In this respect, several literatures have investigated the effects of temperature on the UCL in the RE-doped perovskite-type oxides.…”

Up-convertion (UC) perovskite Er 3+ -doped PbTiO 3 (Er-PTO) nanoparticles with green and red emissions were synthesized via the hydrothermal method. The UC properties were manipulated by adjusting the concentration of Er 3+ ions dopant. The green emission intensity was decreased as the doping concentration increased from 1% to 4% (mole fraction), whereas the red emission intensity was increased. The influences of Er 3+ ions on the temperature-sensing performance were further investigated. The results demonstrated that Er-PTO nanoparticles with doping 1% Er 3+ ions possessed a sensitivity of 3.1 × 10 -3 K −1 at 475 K, presenting a high potential in optical heating devices.
