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...

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...

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 ...

Glass sample of Zinc Lithium Bismuth Borate (25−x) Bi2O3:20Li2O:20ZnO:35B2O3:xPr6O11, (where x = 1, 1.5 and 2 mol%) has been prepared by melt-quenching technique. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction. The absorption spectra of three Pr3+ doped zinc lithium bismuth borate glasses have been recorded at room temperature. The observed optical spectra...

Abstract In this study, the X-ray shielding competence of 15Bi 2 O 3 + 75H BO 10Sm , 10Nd and 10CeO glasses was investigated using Phy-X/PSD simulation software validated XCOM software. The Sm 3+ -doped bismuth-borate glass gave highest linear attenuation coefficients effective atomic number, lowest half-value layer, tenth-value mean free path. Thus, it is most radiation material compared to Nd...

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...

Glasses having compositions 20B2O3.(79.5-x) Bi2O3.xSiO2 (10 ≤ x ≤ 40, mol%) doped with 0.5 mol% of Nd ions were prepared by melt quench technique. The amorphous nature of the glasses was confirmed by X-ray diffraction studies. The spectroscopic properties of Nd ions in borate bismuth silicate glasses as a function of bismuth oxide were investigated using optical absorption and fluorescence spec...
