Effect of TiO2 on the photocatalytic properties of bismuth oxide.
Environ. Technol. 35(9-12) , 1520-4, (2014) Bi2-xTixO3+x/2 (x = 0.05, 0.10 and 0.15) photocatalysts are prepared by solid-state technique. The band gap of the prepared sample was estimated from the onset of UV-Vis absorption spectra. The photocatalytic activities of as prepared samples are investigated... |

Citrate milling of oxides: from poly-dispersed micron scale to nearly mono-dispersed nanoscale.
Phys. Chem. Chem. Phys. 15(14) , 5091-6, (2013) Complex (multivalent/mixed valent) oxides involving two or more cations (e.g. ABO3, AB2O4 and A2B2O7) exhibit the most fascinating range of physical and chemical properties amongst the family of materials systems. There is growing interest in nanoscale forms ... |

Spectroscopic investigations of Er3+ :CdO-Bi2 O3-B2O3 glasses.
Luminescence 27(5) , 334-40, (2012) This article reports on the optical properties of Er3+ ions doped CdO-Bi2O3-B2O3 (CdBiB) glasses. The materials were characterized by optical absorption and emission spectra. By using Judd-Ofelt theory, the intensity parameters Ω(λ) (λ = 2, 4, 6) and also osc... |

Effects of calcination temperature and acid-base properties on mixed potential ammonia sensors modified by metal oxides.
Sensors (Basel.) 11(2) , 2155-65, (2011) Mixed potential sensors were fabriated using yttria-stabilized zirconia (YSZ) as a solid electrolyte and a mixture of Au and various metal oxides as a sensing electrode. The effects of calcination temperature ranging from 600 to 1,000 °C and acid-base propert... |

Effect of Bi2O3 on spectroscopic and structural properties of Er3+ doped cadmium bismuth borate glasses.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 83(1) , 94-9, (2011) Glasses with composition 20CdO·xBi(2)O(3)·(79.5-x)B(2)O(3) (15≤x≤35, x in mol%) containing 0.5 mol% of Er(3+) ions were prepared by melt-quench technique (1150°C in air). The amorphous nature of the glasses was confirmed by X-ray diffraction. The spectroscopi... |

Near-infrared to mid-infrared photoluminescence of Bi2O3-GeO2 binary glasses.
Optics Letters 37(20) , 4260-2, (2012) Near-infrared and mid-infrared (MIR) ultrabroad emission bands were observed in as-grown and annealed Bi(2)O(3)-GeO(2) binary glasses, in the wavelength ranges of 1000-1800 nm and 1800-3020 nm, respectively. The MIR emission band could appear through high dop... |

Low threshold power density for the generation of frequency up-converted pulses in bismuth glass by two crossing chirped femtosecond pulses.
Opt. Express 19(13) , 12039-44, (2011) We investigated the generation of frequency up-converted femtosecond laser pulses by nondegenerate cascaded four-wave mixing (CFWM) in a bismuth-oxide glass (BI glass). Broad-bandwidth light pulses with different propagation directions were simultaneously obt... |
