Temperature sensing performance based on up-conversion luminescence in hydrothermally synthesized Yb3+, Er3+ co-doped NaScF4 phosphors NaScF4:Yb3+, Er3+ crystals were successfully hydrothermally synthesized using distilled water as a single solvent. The phase and morphology were characterized by XRD and SEM. Compared with organic solvents such as ethanol, ethylene glycol and ether, the molar ratio of Na/F/Sc plays an important role in the synthesis process of NaScF4 crystal.

Lanthanide ions-doped Ba3Sc2F12 phosphor: hydrothermal synthesis, morphological control, energy transfer and temperature sensing performance The Ba3Sc2F12 crystals was synthesized by a facile one-step hydrothermal method with Ba/Sc raw material ratio of 3:2. With the F/Sc ratio increasing from 4 to 8, the obtained crystal’s morphology evolved gradually from strip to chocolate shape; then using of the additive from CTAB to EDTA, the obtained crystal’s morphology changed from strip to cubic.
