Abstract
A novel Er3+-doped fluorotellurite titanate glasses with the basic molar composition 75TeO2- 5Nb2O5- 5Bi2O3- 5TiO2- 10PbF2, 75TeO2- 5Nb2O5- 5Bi2O3- 5TiO2- 10PbF2- 10000 ppm Er2O3 and 75TeO2- 5Nb2O5- 5Bi2O3- 5TiO2- 10PbF2- 20000 ppm Er2O3 are explored with respect to possible applications as optical amplifiers. Their thermal and optical features were determined using differential scanning calorimetric (DSC), and UV–Vis–NIR spectroscopy, respectively. The glasses transition temperature Tg, factor against crystallization S, optical energy gap and quantum efficiency were determined. Judd-Oflet parameters Ωt (t = 2, 4, 6), branching ratio, β, fluorescence full width at half maximum (FWHM) of NIR emission, and life time τ, of I13/2 level have been evaluated. The glasses were characterized by a higher values of FWHM of NIR emission at 1.53 μm under excitation by wavelength 980 nm with respect to other glasses system doped by single Er3+ions. In the future these glasses can be fabricated as broadband fiber amplifier for the optical communication devices. The glasses studied glasses exhibit green emission under excitation wavelength of 445 nm. © 2018 Elsevier B.V.
