“…806580650H-5 Generally, the optical properties of oxide Titanium structured surfaces are highly dependent on the presence of defects (including oxygen vacancies) as well as the electron recombination lifetime is largely influenced by the Characteristics of nonporous films especially trap site distribution and density.22 Oxide TiO 2 nanoparticles, showing a large deviations from stoichiometry 19 and representing a high level of defect states, possess a characteristic exponential distribution of mid band gap states, and exhibit different kinetics of electron injection and recombination than nanocrystalline semiconductors . 22, 23 Hence sphereoxide TiO 2 work as a cation of light elements that are formed in a metal lattice when their valence electrons undergo transitions to cooperative states 24. …”

In this study, we report a simple, precise, and nano-scale fabrication technique for oxide nanosphere structure rutile (TiO 2 ) 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 TiO 2 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 (TiO 2 ). The growth of TiO 2 nanostructure is highly recommended for the applications of dye-sensitized solar cells and photovoltaic applications.
