Doped 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 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 and electronic properties of bismuth-implanted glasses
Photoluminescence (PL) and excitation spectra of Bi melt-doped oxide and chalcogenide glasses are very similar, indicating the same Bi center is present. When implanted with Bi, chalcogenide, phosphate and silica glasses, and BaF2 crystals, all display characteristically different PL spectra to when Bi is incorporated by melt-doping. This indicates that ion implantation is able to generate Bi c...
متن کاملSynthesis 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...
