NIR luminescence from Er3+/Yb3+, Tm3+/Yb3+, Er3+/TM3+ and Nd3+ ions-doped zincborotellurite glasses for optical amplification

resumo

In this paper, we report the near-infrared luminescence from the Er3+/Yb3+, Tm3+/Yb3+, Er3+/Tm3+ and Nd3+ ions-doped TeO2-ZnO-B2O3-Li2O-Na2O glasses for optical amplification. The X-ray diffraction (XRD) and differential scanning calorimetry (DSC) profiles of the host glass matrix have been carried out. From the DSC thermogram, glass transition (T-g), crystallization (T,) and melting (T,,) temperatures have been evaluated. The near-infrared spectra of Er3+/Yb3+, TM3+/Yb3+, Er3+/Tm3+ and Nd3+ ions-doped glasses have shown full-width at half-maxima (FWHM) around 58, 127, 87 and 35 nm, respectively. These glasses with better thermal stability and broad near-infrared emissions should have potential applications in broadly tunable laser sources and broadband optical amplification at low-loss telecommunication windows.
