Structural Investigation, Physical and Optical Properties of Mixed Alkali Bismuth Borate Glasses
Lead free, eco-friendly bismuth borate glasses doped with alkali oxides of composition xLi2O+(30-x)Na2O+55B2O3+15Bi2O3 (x = 5,10,15,20,25) were prepared by melt quenching technique. Amorphous nature of glasses was confirmed by X-ray diffraction. Density measurements were carried out at room temperature by standard principle of Archimedes with Xylene as an immersion liquid. The non-linear ...
متن کاملOptical and Thermal Properties of Mixed Alkali Phosphate Based Glasses
Glassy samples with a composition of 40P2O5–30V2O5–(30-x)Li2O– xK2O, 0<x<30 (mol %) were prepared by the conventional melt quenching technique in two forms of bulk and blown film. X-ray diffraction patterns corroborated the amorphous feature of the samples. Density of samples was investigated by using Archimedes principle. Based on absorption and reflection spectra, indirect a...
متن کاملOptical Basicity and Polarizability of Nd3+-Doped Bismuth Borate Glasses
This paper reports on different physical and optical properties of Nd3+-doped bismuth borate glasses. The glasses containing Nd3+ in (25 − x)Bi2O3:20Li2O:20ZnO:35B2O3:xNd2O3 (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. The physical parameters like dielectric constant, refractive index, ion...
متن کاملOptical spectroscopy of Eu3+ doped zinc borate glasses
Zinc borate binary glasses of composition 4Zn0.3B,03 undoped and doped with 0.5% mol of Eu3' were prepared from the melt giving rise to samples of excellent optical quality. In the present work we use the spectroscopic properties of the Eu3' to obtain information about the structural and dynamic features of our system. Different optical techniques such as site selection, excitation spectroscopy...
متن کاملMechanical Properties of Alkali Borate Glasses
A GLASS is, formally, a solid that solidifies without a well-defined melting point— defined as a singular temperature at which there occurs a discontinuous change in a physical property, for example specific volume, during transition between a liquid state and its corresponding solid state—but instead exhibits a continuous change in that property over a range of temperature. Glasses tend to inh...
