“In the field of materials science, researchers have prepared ZrO2: Yb3+/Er3+materials using urea assisted co precipitation method, and investigated the effect of Yb3+/Er3+doping on the crystal structure of ZrO2 through X-ray diffraction technology. It was found that doping leads to the transformation of ZrO2 crystal structure. At the same time, the luminescence thermal stability and temperature sensing characteristics of ZrO2: Yb3+/Er3+were studied, and temperature sensing based on multiple fluorescence intensity ratio signals was achieved, improving the accuracy of temperature measurement.”
