Improving Optical Temperature Sensing Performance of Er3+ Doped Y2O3 Microtubes via Co-doping and Controlling Excitation Power

Abstract This work presents a new method to effectively improve the optical temperature behavior of Er3+ doped Y2O3 microtubes by co-doping of Tm3+ or Ho3+ ion and controlling excitation power. The influence of Tm3+ or Ho3+ ion on optical temperature behavior of Y2O3:Er3+ microtubes is investigated...

The influence of Tm3+ or Ho3+ ion on optical temperature behavior of Y2O3:Er3+ microtubes is investigated by analyzing the temperature and excitation power dependent emission spectra, thermal quenching ratios, fluorescence intensity ratios, and sensitivity. It is found that the thermal quenching of Y2O3:Er3+ microtubes is inhibited by co-doping with Tm3+ or Ho3+ ion, moreover the maximum sensitivity value based on the thermal coupled 4S3/2/2H11/2 levels is enhanced greatly and shifts to the high temperature range, while the maximum sensitivity based on 4F9/2(1)/4F9/2(2) levels shifts to the low temperature range and greatly increases.
