The growing challenges of environmental purification by solar photocatalysis, precious metal free catalysis and photocurrent generation in photovoltaic cells are receiving the utmost global attention. Here we demonstrate the one-pot green chemical synthesis of a new stable heterostructured, eco-friendly, multifunctional micro-composite consisting of α-Bi2O3 micro-needles intercalated with ancho...

Semiconducting polymers have previously been used as the transduction material in X-ray dosimeters, but these devices have a rather low detection sensitivity because of the low X-ray attenuation efficiency of the organic active layer. Here, we demonstrate a way to overcome this limitation through the introduction of high density nanoparticles having a high atomic number (Z) to increase the X-ra...

in this research work the solid-solutions of (bi2o3)1-x (co2o3)x, [x= 0.05, 0.1] (1), (bi2o3)1-x (ho2o3) x, [x= 0.025, 0.05] (2), and (bi2o3)1-x-y (co2o3)x (ho2o3)y, [x=0.05] ; [y= 0.01, 0.02] (3) have been synthesized  using sol-gel method. the effects of transition metal oxides doping on the crystallization and phase transition of the bi2o3 were discussed by x-ray diffraction (xrd). the xrd p...

Bismuth oxide may be a promising battery material due to the high gravimetric (690 mAh g(-1)) and volumetric capacities (6280 mAh cm(-3)). However, this intrinsic merit has been compromised by insufficient Li-storage performance due to poor conductivity and structural integrity. Herein, we engineer a heterostructure composed of bismuth oxide (Bi2O3) and bismuth sulphide (Bi2S3) through sulfuriz...

This paper deals with a synthesis of new ionising radiation attenuation composite material from Lu2O3 - Bi2O3 nanoparticles structure, that has never been described yet. The describes the preparation nano- and microparticles by three methods: self-combustion synthesis, solid-state method coprecipitation method. Polymer solution was prepared Polyvinyl Butyral. Afterwards, nanofibers were process...

Intensely yellow β -bismuth trioxide in the form of about 41 nm large crystallites has been prepared by thermal decomposition of (BiO)2CO3 at 400 ◦C. From the band gap energy of 2.3 eV obtained under the assumption of an indirect band-to-band transition and the quasi-Fermi level of −0.28± 0.02 V (vs. NHE) a valence band edge position of 2.02 V is calculated. This semiconducting oxide assists a ...

The aluminum coordination state in bismuth doped silica glass, which has new broad infrared emission at 1.3 lm regions, was investigated by using Al NMR, and it is demonstrated that 6-fold coordinated aluminum ions with corundum structure are dominant in bismuth doped silica glass until Bi2O3 concentrations of 1.0 mol% with Al2O3. The aluminum ion efficiently affects the creation of a Bi lumine...

BACKGROUND In fabrication of ZnO-based low voltage varistor, Bi2O3 and TiO2 have been used as former and grain growth enhancer factors respectively. Therefore, the molar ratio of the factors is quit important in the fabrication. In this paper, modeling and optimization of Bi2O3 and TiO2 was carried out by response surface methodology to achieve maximized electrical properties. The fabrication w...

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...
