Abstract

In this study, we report a simple, precise, and nano-scale fabrication technique for oxide nanosphere structure rutile (TiO₂) using couple hundred of femtosecond laser irradiation at MHz pulse repetition frequency in air at atmospheric pressure. Measured reflectance's through Spectroradiometer show that their couplings of incident electromagnetic irradiations are improved greatly over the broad band wavelength range. Lower reflectance intensity obtained with long dwell time is due to generate bulk quantity of TiO₂ oxide nanoparticle agglomerate by fusion, and form interweaving fibrous structures that show certain degree of assembly. The X-ray diffraction test confirmed that the oxide titanium metallic nanostructure is a rutile phase (TiO₂). The growth of TiO₂ nanostructure is highly recommended for the applications of dye-sensitized solar cells and photovoltaic applications.
