Bismuth (III) oxide is an important compound of Bismuth, Bismuth oxide has two kinds of crystal structure: Alpha type and Beta type. Compared with beta Bismuth oxide, alpha Bismuth oxide is more stable in high temperature and has more common use of electronic materials, thermistor, glass coloring, varistor, surge arresters, CRT, fireproof paper ...

Due to overlay of bismuth oxide thin film on both substrates, a shift in the resonance frequency towards higher frequency end was observed. As thickness of film increased the peak output decreased in both cases. The peak output due to bismuth oxide thin film on alumina was higher as compared to peak output due to bismuth oxide thin film on glass.
Weigh out 2.6 g (0.01 mol) of bismuth(III) oxychloride. Dissolve the bismuth(III) oxychloride in 3 cm 3 of concentrated hydrochloric acid in a boiling tube or small beaker. This will give a clear solution of bismuth(III) chloride. Line up on the demonstration bench six beakers of the sizes shown containing water as shown in the table.
When bismuth oxide species were deposited on silica separately (2Bi-SiO 2), it also stabilized in small-size without any diffraction peaks of Bi/Bi 2 O 3 in XRD profiles (Fig. 1d).
The utility of the method is illustrated by estimating the Raman stretching frequencies for ideally symmetric bismuth oxide structures BiO 4, BiO 5, BiO 6, BiO 7, and BiO 8. As a final, practical example the method is used to determine the bond lengths and coordinations of the bismuth oxide species in the β- and δ-phases of Bi 2 O 3.
Diffuse reflectance UV-Vis spectrophotometry was used to determine the band gap of the bismuth oxide nanoparticles and unprecedented blue shifts (due to quantum confinement) as compared to bulk a ...
Bismuth(III) oxide is perhaps the most industrially important compound of bismuth.It is also a common starting point for bismuth chemistry. It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores. Dibismuth trioxide is commonly used to produce the "Dragon's ...
The light absorption edges shifted from∼500 nm, to ∼578 nm and ∼450 nm for S1, S6 and S9 samples, ... Bismuth oxide nanoparticles decorated Graphene layers for the degradation of Methylene blue dye under visible light irradiations and antimicrobial activities. J. Environ. Chem.
We report the first experimental demonstration of Bragg grating-based nonlinear switching in a bismuth-oxide single-mode fiber. Exploiting the strong χ(3)-nonlinearity of this fiber in a cross-phase modulation scheme, we change the transmission of a probe near the grating stop band from 90 % to 20 %, a 6.5 dB extinction ratio, at powers as low as 55 W. This is an 18-fold improvement in the ...
We demonstrate widely tunable wavelength conversion based on four-wave mixing using a dispersion-shifted bismuth-oxide photonic crystal fiber (Bi-PCF). A 1-meter-long Bi-PCF is used as the nonlinear medium for wavelength conversion of a 10 Gb/s non-return-to-zero (NRZ) signal.

We demonstrate widely tunable wavelength conversion based on four-wave mixing using a dispersion-shifted bismuth-oxide photonic crystal fiber (Bi-PCF).
Bismuth oxide (Bi2O3) is a well-known transition metal oxide with varied interesting character- istics such as its thermal, energy band gap, photocon- ductivity, large surface area, and good electrochemical stability (Li and Yan 2009; Periasamy et al. 2011; Chen et al. 2009).
Preparation of new stabilized, oxide ion-conducting, bismuth vanadate phases by a microwave assisted method, from V 2 O 5, Bi 2 O 3 and other solid oxides, was reported. These ceramics show promise in solid oxide fuel cells, water-vapor electrolyzers and oxygen sensors.
