Research ArticleOpen accessPhrase in the titleNew approach between the Optical Basicity and the Dielectric Constant through the Molar Polarizability for Some Binary GlassesEl-Sayed MoustafaProblem statement: In the present study, a new correlation between the optical basiciry which describes the electronic charge clouds around the oxide glass and the dielectric constant has been proposed through the molar polarizability of the binary oxide glasses. Approach: Two experimental forms have been suggested relating the optical basicity and the molar electronic polarizability. Hence, the dielectric constant and … …Physics International, Vol. 2, Issue 1 · 26 Oct 2011 · 7,764 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComposition Dependent Structural and Thermal Properties of SM2O3 Doped Zinc Fluoroborate GlassesSudha D. Kamath, Akshatha Wagh, M.P. AjithkumarGlasses based on Sm3+ doped zinc fluoroborate have been synthesized and characterized. Formation of glass has been investigated in the 30 ZnF2-20 TeO2-(50-x) B2O3-x Sm2O3 matrix. Fast quenching is required to prevent melt crystallization and adequate heat treatment to diminish thermal stress, which results in an efficient amorphous material. The Differential Scanning Calorimeter (DSC), Scanning Electron Microscopy (SEM), Energy Dispersive … …Energy Research Journal, Vol. 4, Issue 2 · 15 Jul 2014 · 7,244 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptical Investigation and Electronic Polarizability of Nd3+ Doped Soda-Lime-Silicate GlassesP. Chimalawong, J. Kaewkhao, P. LimsuwanProblem statement: This study researched on different physical and optical properties of Nd3+ doped soda-lime-silicate glass. The glasses containing Nd3+ in (65-x)SiO2: 25Na2O: 10CaO: xNd2O3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd2O3 concentration due to increasing of Non Bridging Oxygen (NBOs) in glass matrix. The optical … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,149 accessesView PDF Cite
