Annotation

The cubic phase NaYF4:Pr3+, Yb3+ single crystals were grown in the resistive furnace by the Bridgman- Stockbarger technique with following milling in an agate mortar. The luminescence intensity ratio (LIR) between 3P1 – 3H5 and 3P0 – 3H5 emissions of Pr3+ was taken a temperature-dependent parameter. The calculated absolute (Sa) temperature sensitivity was 0.0075 at 320 K. The LIR between 3P0 – 1G4 (Pr3+) and 2F5/2 – 2F7/2 (Yb3+) emissions is also temperature-dependent due to phonon-assisted nature of energy transfer between 1G4 of Pr3+ and 2F5/2 of Yb3+. Sr and Sa demonstrated the highest values in the 100–220 K temperature range (Sa (max) = 0.0047 K􀀀 1 at 150 K). NaYF4:Pr3+, Yb3+ samples are useful in optical temperature sensing in the broad temperature range from 100 up to 320 K.
