Abstract
The new Er3+/Yb3+ co-doped 70TeO2-5Li2O-(25âx)B2O3-xGeO2(x = 0, 5, 10, 15 fand 20Â mol.%) glasses were prepared. The thermal stability, absorption spectra, emission spectra and lifetime of the 4I13/2 level of Er3+ ions were measured and studied. The FT-IR spectra were carried out in order to investigate the structure of local arrangements in glasses. It is found that the thermal stability, absorption cross-section of Yb3+, emission intensity and lifetime of the 4I13/2 level of Er3+ increase with increasing GeO2 content in the glass composition, while the fluorescence width at half maximum (FWHM) at 1.5Â um of Er3+ is about 70Â nm. The obtained data suggest that this system glass can be used as a candidate host material for potential broadband optical amplifiers.
