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...

This study presents a novel visible light-active TiO₂ nanotube anode film by sensitization with Bi₂O₃ nanoparticles. The uniform incorporation of Bi₂O₃ contributes to largely enhancing the solar light absorption and photoelectric conversion efficiency of TiO₂ nanotubes. Due to the energy level difference between Bi₂O₃ and TiO₂, the built-in electric field is suggested to be formed in the Bi₂O₃ ...

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...

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...

Construction of heterojunction and decoration cocatalyst are two vital strategies to accelerate migration charge carriers. However, the fabrication routs multi-composites usually complex expensive. In this work, Bi2O2CO3/Bi2O3/Bi ternary composite was fabricated via a facile one-step redox reaction. Ethylene glycol selected as solvent during whole reaction process. Moreover, ethylene an excelle...

Phase-pure BiCuOSe, which is isostructural to the layered p-type transparent conductor LaCuOS, has been synthesized in high yield by a single-step hydrothermal reaction at low temperature (250 degrees C) and pressure (<20 atm). A moderate reaction temperature of 250 degrees C was sufficiently high to solubilize both Bi2O3 and Cu2O and stabilize monovalent copper and low enough to impede the oxi...

The formation mechanisms of pyrochlore-type Bi2Co1/2Cr1/2Nb2O9+Δ (space group Fd-3m, a = 10.4838(8) Å), in the temperature range from 400 to 1050 °C were studied by employing X-ray diffraction, scanning electron microscopy and energy-dispersive spectroscopy. An extensive reaction between binary metal oxides was found begin at temperatures above 550 °C, following transition monoclinic α-Bi2O3 in...
