Synthesis and Characterization of Lithium Borate Glasses Containing Bismuth
A lithium bismuth borate glass system is prepared by the conventional melt quenching technique. The Powder X-Ray diffraction analysis of the prepared samples confirms the amorphous nature of the samples. The density and molar volume studies report the change of structure with the increase of bismuth content. The FTIR analysis of the samples revealed that the network structure of the prepared sa...
متن کاملStructural Characterization of fly ash doped lithium borate Glasses
Lithium borate glasses with fixed alkali content of 10 Mole % and different modifiers have been prepared. To compare the role of fly ash as a glass modifier the content of glass modifier PbO, Al2O3 have been kept same to 5 mole %. To investigate the structure FTIR and UV-VIS spectra of prepared samples have been taken. From optical data optical band gap and cutoff wavelength have been calculate...
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 کاملions 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...
متن کاملSynthesis and Structural Characterization of Nickel Substituted Manganese Zinc Nanoferrites
Magnetic oxides are naturally occurring minerals. In order to understand their unique properties and their utilization in technological applications, one must fully understand the correlation between chemistry, structure, particle size and processing. Among the broad classification of magnetic oxides, the spinel ferrites gain much importance because of their low cost, high magnetic permeability...
