“…The energy gap are also resumed in Table . These values are comparable to those reported in the literature for phosphate glasses . A decrease of the gap occurs from 4.00 to 3.40 eV with the increase in Ta 2 O 5 concentration in the glass and 2.9 eV after the glass‐ceramic formation.…”

“…These values are comparable to those reported in the literature for phosphate glasses. [44][45][46] A decrease of the gap occurs from 4.00 to 3.40 eV with the increase in Ta 2 O 5 concentration in the glass and 2.9 eV after the glass-ceramic formation. Such variation occurs due to the TaO 6 polyhedra formation which increases the network connectivity and glass overall polarizability, corroborating the DSC, FTIR, and Raman data.…”

Transparent and homogeneous tantalum phosphate glasses were prepared in the binary system (100‐x)NaPO3‐xTa2O5 with x varying from 10 to 50 mol%. Thermal, structural, and optical properties, as well as crystallization mechanisms, were investigated by thermal analysis, X‐ray diffraction, Fourier‐transform infrared spectroscopy (FTIR) and Raman spectroscopies, optical absorption, transmission electron microscopy in terms of Ta2O5 content. FTIR and Raman results support the tantalum insertion in the phosphate chains with [TaO6] polyhedra cross‐linking the phosphate units. At higher Ta2O5 content, [TaO6] clusters are formed and connected to the phosphate network by P‐O‐Ta bonds. This structural evolution is in good agreement with the thermal features measured by differential scanning calorimetry (DSC) with a strong increase of the Tg temperatures up to 920°C, high thermal stability against crystallization for low Ta2O5 content and increasing of crystallization tendency for the most Ta‐concentrated samples. Besides, due to the progressive insertion of [TaO6] units, the precipitation of Na2Ta8O21 perovskite‐like phase was identified in the sample with 50 mol% of Ta2O5. The optimal heat treatment conditions were identified using DSC measurements and a transparent glass‐ceramic from 50NaPO3 to 50Ta2O5 composition was prepared. The obtaines glass‐ceramic has great potential for optical applications, such as host for rare‐earth ions, nonlinear optical materials, and ferroelectric domain.

“…The third peak at the wavenumber of 724 cm −1 is a result of the motion of Ge–O two non-bridged oxygen atoms in GeO 4 tetrahedral units [29,30], thereby this absorption band indicates the maximum phonon energy (MPE) of produced bismuth-germanate host glass. The value of MPE is smaller in comparison to silicate (963 cm −1 ) [31], germanate (1002 cm −1 ) [32], phosphate (1345 cm −1 ) [33], borate (1602 cm −1 ) [34], and comparable to other bismuth glasses (926–1183 cm −1 ) [35,36].…”

Bismuth-germanate glasses with low hydroxide content co-doped with Ho3+/Yb3+ ions have been investigated in terms of structural and spectroscopic properties. To reduce OH- ions content and improve transmittance value at the wavelength of 3.1 µm, the glass synthesis has been carried out in low vacuum conditions (45–65 mBar). The composition of the host glass based on heavy metal oxides affects the maximum phonon energy (hωmax = 724 cm−1), which low value has a positive impact on the mid-infrared emission parameters. Emission band at the wavelength of 2.87 µm was observed in glass co-doped with mol% 0.25 Ho2O3/0.75 Yb2O3 under 980 nm high power laser diode wavelength excitation. Lifetime measurements of the Yb3+:2F5/2 quantum level indicate efficient Yb3+ → Ho3+ energy transfer (η = 61%). The developed active bismuth-germanate glass was used as the core of optical fibre operating in the mid-infrared region.

“…Rare-earth ions doped glass-ceramics are important materials for optical fibers, wave guide lasers, sensors and optical amplifiers [1][2][3][4][5].Oxide glasses are the most stable host matrices for practical applications due to their high chemical durability and thermal stability [6][7][8][9][10].Phosphate glasses are extremely attractive materials for linear and non-linear application in optics, due to their important aspects such as their low melting temperature, low phonon energy, high refractive index, high dielectric constant, good chemical durability, high thermal stability, good solubility of rare earth ions [11][12][13][14][15][16].The addition of heavy metal oxide to phosphate glasses decreases the phonon energy. Thus, leads to increase in its quantum efficiency of luminescence from the exited state of rare earth ions .Er 3+ doped rare earth doped glasses considerable literature has recently emerged concerning the structure, optical, mechanical, thermal, and electrical properties [17][18][19][20].…”

Zinc lithium calcium potassiumniobate phosphate glasses containing Er3+ in (45-x): P2O5:10ZnO:10Li2O:10CaO:10K2O:15Nb2O5:xEr2O3. (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by x-ray diffraction studies. Optical absorption, Excitation, and fluorescence spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross– section of various emission lines have been evaluated.
