“…Tellurite glasses have been shown [2,4,5] to be candidates as Er 3+ hosts to substitute or complement the silica-based glasses, as they combine a 4 I 13/2 ! 4 I 15/2 emission bandwidth as broad as 60 nm, extended to 1630 nm, with acceptable properties for fiber drawing and planar waveguide fabrication.…”

“…While, the band at 668 cm -1 is assigned to asymmetric vibrations of the network generated by TeO 4 triagonal bypyramid (tbp) groups, which were linked through Te-OTe, with O occupies alternative axial and equatorial positions [19]. The band around 744 cm -1 arises from the stretching vibrations of TeO 3 and TeO 3+1 triagonal pyramids [20,21].…”

Multicomponent tellurite glasses containing altered concentrations of Er 2 O 3 (ranging from 0 to 1 mol%) were prepared by the standard melt quenching technique. Investigations through energy dispersive X-ray spectroscopy (EDS), Raman scattering spectroscopy, FTIR spectroscopy, NIR emission studies and dielectric measurement techniques were done to probe their compositional, structural, spectroscopic and dielectric behaviour. The influence of erbium ion concentration on the infrared emission (~1.53 m) of these glasses and their respective lifetimes were measured. From the measured capacitance and dissipation factor, the relative permittivity, dielectric loss and the conductivity were computed; which furnish the dielectric nature of the multicomponent tellurite glasses that depend on the frequency of the applied LCR meter. Assuming the ideal Debye behaviour as substantiated by Cole-Cole plot, an examination of the real and imaginary parts of impedance is performed. The power-law and Cole-Cole parameters were resolved for all the glass samples. From the assessment of the NIR emission analysis and dielectric properties of the glass samples, it is manifested that the Er 3+ ion concentration has played a vital role in tuning the optical and dielectric properties and the 0.5 mol% Er 3+-doped glass is confirmed as the finest composition.
