Mid-infrared emission and Raman spectra analysis of Er(3+)-doped oxyfluorotellurite glasses. Academic Article uri icon


  • This paper reports on the spectroscopic and structural properties in Er(3+)-doped oxyfluorotellurite glasses. The compositional variation accounts for the evolutions of Raman spectra, Judd-Ofelt parameters, radiative properties, and fluorescent emission. It is found that, when maximum phonon energy changes slightly, phonon density plays a crucial role in quenching the 2.7 m emission generated by the Er(3+):(4)I11/2(4)I13/2 transition. The comparative low phonon density contributes strong 2.7 m emission intensity. The high branching ratio (18.63%) and large emission cross section (0.9510(-20)cm(2)) demonstrate that oxyfluorotellurite glass contained with 50 mol.% TeO2 has potential application in the mid-infrared region laser.
