“…Density measurements are sensitive to structural changes of glass network. It is affected by structural softening, compactness, changes in the geometrical configuration, co‐ordination number, and dimensions of interstitial spaces of the glass . The density is calculated using Equation ,

ρ = \frac{W_{normala}}{W_{normala} - W_{normalb}}

where, W a is the weight of glass sample in air, W b is its weight in acetone and

ρ_{1}

is the density of the acetone.…”

This paper reports on the effect of varying concentration of erbium (Er 3þ ) on the (70-x/2) TeO 2 À (20-x/2) B 2 O 3 À10 ZnO À x Er 2 O 3 (where x ¼ 0, 0.5, 1.0, 2.0, 2.5 mol.%) system, fabricated using the conventional melt quenching technique. The impact of Er 3þ on the structural, physical, and optical properties of these zinc borotellurite glasses is investigated using Fourier transform infrared spectroscopy (FTIR), density measurements and UV-vis spectroscopy. The amorphous nature is confirmed using X-Ray diffraction. FTIR results reveal that the glass is formed of fundamental borate and tellurite network units. The addition of Er 2 O 3 results in the formation of TeO 3 at the expense of Te-O-Te linkage. The UV-vis spectroscopy results show that Er 3þ enter the glass matrix showing absorption peaks corresponding to 4f-4f transitions of trivalent Erbium ions (Er 3þ ) from ground state 4 I 15/2 to the excited states 4 F 5/

“…Our prior analysis and exploration illustrate that the prepared tellurite glasses have fine integrities for visible luminescence [11]. In order to accomplish erbium doped glasses for broad band and gain amplification, it is crucial to evaluate the full width at half maximum (FWHM) and stimulated emission cross-section of 1.53 m band.…”

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.

“…In contrast, as a kind of oxide glasses, tellurite glass is characterized by a number of advantages such as good chemical durability, high rare-earth solubility (10-50 times larger than in silica), wide transmission window (typically 0.4-6 µm), low phonon energy (~750 cm -1 ) and high refractive index (~2.0). The low phonon energy of glass host results in the low non-radiative relaxation rates between the excited levels and in turn improves the luminescent quantum efficiency, and high refractive index can improve both the stimulated absorption and emission cross-sections of rare-earth ions [16][17][18][19].…”
