  • Study on synthesis and photocatalytic activity of novel visible light sensitive photocatalyst Ag

    Silver orthophosphate nanoparticles have been synthesised by precipitation of AgNO3 and H3PO4 in presence of oleylamine and other solvents like toluene, and ethanol at room temperature. Particle sizes of silver orthophosphate nanocrystals can be controlled by adjusting the amount of water. The ...

  • Preparation and characterisation of CaO–Bi
    complex oxide

    Ca4Bi6O13 powders prepared from a citric acid complex were characterised by X–ray diffraction, UV–vis diffuse reflectance spectra and specific surface area measurements. In a citric acid complex method, the single phase of Ca4Bi6O13 crystal was obtained at 700°C in air. The Ca4Bi6O13 powders calcined ...

  • Study of the effect of post-irradiation with low linear energy transfer on optical and spectral response of CR-39 polymeric material

    The optical properties of CR-39 polymer track detectors irradiated with high Linear Energy Transfer (LET) (alpha particles at energies 3.05 MeV and 4.86 MeV) and followed by low LET (gamma ray irradiation at different doses ranging from 0 to 200 kGy) were investigated. The chemical etching was verified for all samples. Also, the optical properties were studied with an Ultraviolet-Visible (UV-VIS) ...

  • Water and environmental analysis according to US EPA regulations using the lambda 25/35/45 UV/Vis spectrophotometers

    UV/Vis spectroscopy is an important analytical technique used for the determination of many water constituents. Environmental regulations in many countries prescribe the use of UV/Vis spectroscopy. Depending on the method, UV/Vis determinations of metal and organic nonmetal analytes in water have a minimum detectability in the ppb-ppm range. The Lambda UV/Vis Spectrophotometers ...
