“…The peak of Al + wasn't indicated in IR absorbance spectra as shown in Fig. 1, because the concentration of Al 3+ was scanty and its signal of vibration frequency was very weak [18] . The groups like di, tri, Penta, meta, and boroxol rings with bridging or non-bridging oxygen ions participate in the formation of multicomponent borosilicate glasses [25] .…”

This research investigates the influence of the concentration of Sm+ 3 ions on the features of a new borosilicate glass system with the composition 50B2O3– 14SiO2- 20Li2O– 15Na2O– 1.0Al2O3-x(Sm2O3), where x = 100, 200, 300, 400, and 500 ppm. The glasses are characterized by XRD, FTIR, UV- Vis- NIR, and photoluminescence spectra. The XRD results proved that all prepared glass has amorphous nature. Moreover, it was found that the value of density, ρ, and refractive index,n, increase with increasing of Sm+ 3 content. Otherwise, the value of molar volume, optical energy gap, and boron-boron distance decrease by increasing sm+ 3 concentration. The structure of glasses studied was investigated by computing \(Internuclear \left({r}_{i}\right)\), Polaron radius \(\left({r}_{p}\right)\), field strength \(\left(F\right)\) and the deconvolution of FTIR spectra. Judd-Ofelt theory applied to clarify the structural changes and nature of the bonds of prepared glasses. Moreover, A spectroscopic quality factor, the branching ratio (βr), and lifetime (τ) are calculated via the parameters of Judd-Ofelt. The color chromaticity of the present glasses evidenced that the emission was in the white-reddish orange region under 402nm excitation depended on the concentration of Sm3+ ions incorporated into the host glasses. From photoluminescence emission, stimulated emission cross-section, and CIE chromaticity leads to these glasses are promising for light-emitting diode (LED) as; laser material in a wide range.

Neodymium doped Na 2 O-ZnO-TeO 2 (NZT) glasses were prepared by the conventional melt quenching technique.DTA and TG were used to confirmation of glass preparation through the glass transition temperature at 447°C for the glass system. The analysis of FTIR spectra and X-ray diffraction described the nature of the samples were ionic and amorphous respectively. The optical bandgap energy was estimated using absorption spectra and found to be decreased from 2.63eV to 1.32 eV due to the increase of doping concentration. The intensity of the emission spectra was enhanced for the higher concentration of Nd 3+ ions. The dielectric constant of the glass samples was found to be constant for the large range of frequency (3 kHz to 1 MHz). The variation of conductivity with the temperature of the samples had shown the Arrhenius mechanism of conduction.
