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 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 ⁴
