We report on the growth of multiferroic Yb2CoMnO6 and Lu2CoMnO6 single crystals which were synthesized by the flux method with Bi2O3. Yb2CoMnO6 and Lu2CoMnO6 crystallize in a double-perovskite structure with a monoclinic P21/n space group. Bulk magnetization measurements of both specimens revealed strong magnetic anisotropy and metamagnetic transitions. We observed a dielectric anomaly perpendi...

Fe2O3-Bi2O3-B2O3 (FeBiB) glasses were developed as novel pH responsive hydrophobic glasses. The influence of the glass composition on the pH sensitivity of FeBiB glasses was investigated. The pH sensitivity drastically decreased with decreasing B2O3 content. A moderate amount of Fe2O3 and a small amount of B2O3 respectively produces bulk electronic conduction and a pH response on glass surfaces...

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...

Highly aligned 1D n-p type ZnO/Bi2O3 and n-n ZnO/In2O3 heterojunction nanofibers (HNFs) have been developed using coaxial electrospinning approach, aiming at exploring the effect of nanofibrous...

In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...

Annealing of periodic mesoporous organosilica supported with bismuth (Bi@PMOS) and cerium (Ce@PMOS) nanoparticles was carried out to derive oxide (Bi2O3) (CeO2) nanosheets. The hydrothermal sol-gel method used synthesize hexagonal Bi@PMOS Ce@PMOS. These PMOS provided an opportunity for retain a configuration alongside their traditional crystalline phases (tetragonal cubic) in Bi2O3 CeO2 All pro...

A two-dimensional layered CeO2/Bi2O3 composite was synthesized by microwave solvothermal method. X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron microscope (FESEM), transmission (TEM), UV-Vis diffuse reflection spectroscopy (DRS), and photoelectron (XPS) were used to studied crystal structure, morphology, optical performance, elemental composition the surface elect...

3D structured clay filters were synthesized using the printed molds. The Bi2O3 photocatalyst was immobilized on surface of filter sol-gel dip, soak and calcination at 450 °C. X-Ray Diffraction analysis showed growth tetragonal β-Bi2O3 clay. diffused reflectance UV–Vis spectroscopy confirmed presence with a broad optical absorption in visible range an estimated bandgap 2.38 eV. morphology unifor...
