Luminescence thermometry below room temperature via up-conversion emission of Y2O3:Yb3+, Er3+ nanophosphors
Apstrakt
This study explores potential of Er3+-Yb3+ doped phosphors for up-conversion luminescence thermometry in the temperature range from 10 K to 300 K. Yttrium oxide nanopowder doped with trivalent ytterbium and erbium ions (Y1.97Yb0.02Er0.01O3) was prepared by hydrothermal synthesis as an example. The intensity ratios of up-conversion emissions from thermally coupled H-2(11/2) and S-4(3/2) levels of Er3+ show strong temperature dependence (in the range 150 K-300 K) with much higher relative sensitivity than those reported for thermometry above room temperature with Er3+-Yb3+ based up-conversion materials. The maximal value of relative sensitivity is 5.28%K-1 at 150 K, with temperature resolution ranging from 0.81 K to 0.06 K. In addition, the intensity ratios of emission from thermally non-coupled Er3+ levels (H-2(9/2) and F-4(9/2)) and from S-4(3/2) also show temperature dependence that can be approximated with an exponential function. With these up-conversion emission ratios, it is possi...ble measure temperature in the range of 10 K to 300 K with excellent sensitivity and resolution. (C) 2014 AIP Publishing LLC.
