Preparation and Optical Storage Properties of λ­Ti3O5 Powder

doi:10.3724/SP.J.1077.2013.12309

Abstract

Abstract:

The Ti₃O₅ powder was prepared by reducing TiO₂ nanopartical in H₂ atmosphere. The samples were investigated by powder X-ray diffraction (XRD), Fourier transform infrared spectroscope (FTIR), scanning electron microscope (SEM) and UV-Vis diffusion reflectance spectra (UV-Vis). The results show that, single phase Ti₃O₅ can be obtained by increasing the H₂ flow. When H₂ flow increases from 0.3 mL/min to 0.8 mL/min, the single phase λ-Ti₃O₅ can be synthesized using SiO₂-coated TiO₂ (rutile, nanoparticle) as raw material at 1150℃ for 1 h. While using nano-TiO₂ powders without SiO₂-coated as raw material, the reduction product is multiphases composed of λ-Ti₃O₅ and β-Ti₃O₅. There is a high reflectivity contrast between λ-Ti₃O₅ and β-Ti₃O₅. When the multiphases sample is irradiated with 532 nm 20 ns-pulsed laser light at room temperature, Ti₃O₅ will transit from α phase to β phase, which shows a good optical storage performance.
