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.

40 Li2O–5 WO3–(55-[Formula: see text]) B2O3: [Formula: see text]V2O5 (mol%) for [Formula: see text] glasses were prepared by melt-quenching. Electric polarization was described in terms of the dielectric constant ([Formula: see text]) and loss ([Formula: see text]). Mixed conduction phenomenon was explained by redox pairs [Formula: see text] and [Formula: see text] at high temperatures. Electronic polarizability ([Formula: see text]) was determined over a range of frequencies (100[Formula: see text]Hz–100[Formula: see text]kHz) and temperatures (30–[Formula: see text]C). The change of boron coordination in the glass network was explained with the aid of temperature coefficient of polarizability ([Formula: see text]). Nonlinear susceptibility ([Formula: see text]) and optical band gap ([Formula: see text]) were studied as a function of concentration of V2O5. The highest values of [Formula: see text] and [Formula: see text] were obtained at [Formula: see text][Formula: see text]mol%. These glasses may find potential practical applications in the fields of solid-state ionics and nonlinear optics.
