摘 要:In this paper, the glass microsphere co-doped Er3+/Yb3+ was fabricated. Many regularly spaced, sharp peaks appeared in the emission spectra of the glass microspere. We report the laser power induce the spectral shift of the whispering-gallery-modes [WGMs] of a glass sphere. The laser power dependence of the WGMs spectral position is about 0.0252nm/mW under 976nm excitation. Maybe, the glass microsphere can be used as a temperature sensor.
