[{[(TeO2)0.8 (B2O3)0.2]0.8 (SiO2)0.2}0.99 (Ag2O)0.01]1−y – (Er2O3 NPs)y, and y=0.01,0.02,0.03,0.04 and 0.05 mole% were fabricated by the melt quenching technique. X-ray diffraction (XRD) was used to verify and confirm the glasses’ non-crystallinity. X-ray fluorescence (XRF) proved the achievement of silicate of 98.6% quality from rice husk. Fourier transform infrared d (FTIR) results exposed the basic structural […]
Samarium oxide (Sm2O3) and ytterbium oxide (Yb2O3) doped tungsten-tellurite glasses (TWSm), (TWYb) in the forms of 80 (TeO2) – (20-x) (WO3) – x (Sm2O3) and 80 (TeO2) – (20-x) (WO3) – x (Yb2O3) with x = 0, 1.0, 2.0, 3.0, 4.0 and 5.0 mol% were prepared by the melt-quenching technique. The XRD analysis for the […]
AbstractThe study of optical and thermal properties of gadolinium oxide-doped tellurite glass was studied for the first time to the best of our knowledge. Gadolinium oxide-doped tellurite glass system with chemical formula (1 − x)[(TeO2)70(B2O3)30]-x(Gd2O3) with x = 0.2, 0.4, 0.6, 0.8 and 1.0 mol% was prepared by the melt-quenching technique. X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, UV–Vis spectroscopy […]
This work deals with the theoretical analysis of ultrasonic relaxation in the glass system xNb2O5 – (100− x) TeO2 glasses, and 4 ≤ x ≤22.5 mole %. The parameters of the theoretical analysis deal with the transmission of ultrasonic waves through dual-well potential. The parameters are alternate potential energy, centers of energy loss, and elongation […]
