© 2020 Elsevier Ltd and Techna Group S.r.l. New effective luminescence thermometers based on novel host Ba4Y3F17 doped with Pr3+ and Pr3+/Yb3+ in 80–320 K temperature range were studied. The absolute temperature sensitivity (Sa) of both Ba4Y3F17: Pr3+(0.1 mol %) and Ba4Y3F17: Pr3+(0.1 mol.%): Yb3+(10.0 mol.%)nanothermometers based on luminescence intensity ratio (LIR) between two Pr3+ emission bands (3P1-3H5 and 3P0-3H5) demonstrate a notable value (0.011 K−1 at 300 K) in the 200–320 K range. The Ba4Y3F17: Pr3+(0.1 mol.%): Yb3+(10.0 mol.%)nanothermometers based on LIR between 3P0→3H4 of Pr3+ and 2F5/2→ 2F7/2 of Yb3+ emission bands demonstrate high Sa into the 80–200 K range with maximal Sa = 0,0778 K−1 at 100 K. The stability of the phosphors was revealed by thermo-cycling experiments. |
