Abstract

Based on the fluorescence intensity ratio method, the temperature- sensing behavior through thermally coupled levels (TCL) of the ²H_11/2 and ⁴S_3/2 states as well as the sublevels of the ⁴F_9/2 state of Er³⁺ has been studied. The thermometry is observed to be dependent on the pump power for the ²H_11/2 and ⁴S_3/2 states, leading to an error of more than 20 K at 478 K. By utilizing the sub-levels of the ⁴F_9/2 state, such a problem could be solved. The maximum sensitivity is about 0.15% K^-1 at 298 K. This will provide guidance on selecting appropriate and practical TCL for precisely sensing the temperature.
