ions doped zinc bismuth borate glasses
Glasses having composition 20ZnO·xBi2O3·(79-x)B2O3 (15 x 35, in mol%) doped with 1 mol% of Nd 3+ ions were prepared. The different physical and absorption spectral properties have been investigated to understand the variation of the hypersensitive absorption band intensities. From the absorption spectra, Judd-Ofelt intensity parameters, ( = 2, 4, 6) have been calculated and these parameters wer...

Niobium doped silver lead borate glasses with the chemical composition (29-x) PbO-yAg2O70B2O3-xNb2O5 (where x= 0.1 to 0.5mol%, y= 1 to 5 mol %) have prepared by conventional melt quenching method.SEM/XRD technique confines glassy nature of the prepared samples. IR and UV optical absorption technique have been used to obtain the information concerning network structure. From the absorption edge ...
متن کاملDoped Zinc Lithium Bismuth Borate Glasses
Zinc lithium bismuth borate glasses containing Er in (25x): Bi2O3:20Li2O:20ZnO: 35B2O3: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 and fluorescence spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are e...
متن کاملCombined DFT, Deconvolution Analysis for Structural Investigation of Copper –doped Lead Borate Glasses
Samples from binary lead borate glass system doped with minor quantities of copper have been prepared by conventional melt-annealing technique. X-ray diffraction (XRD) has been used to prove the amorphous nature of prepared glasses. Structural and optical properties were investigated using FTIR and UV-vis. Spectroscopic investigations were approved using density function theory (DFT) calculatio...
متن کاملOptical and structural properties of lithium sodium borate glasses doped Dy3+ ions Abstract Absorption and emission spectra of lithium sodium borate glass doped with different concentrations
Absorption and emission spectra of lithium sodium borate glass doped with different concentrations of Dy3+ have been reported. The concentration of Dy3+ was varied from 0.3 to 1.3 mol%. The amorphous nature of the prepared samples was confirmed by the X-ray Diffraction (XRD). Fourier transforms infrared (FTIR) spectra, and other significant physical properties (energy band gap, density, ion con...
