Influence of anatase titania nanoparticles content on optical and structural properties of amorphous silica

Abstract
Abstract In this work, the influence of TiO 2 NPs content on optical and structural properties of amorphous SiO 2 is investigated. Amorphous SiO 2 /TiO 2 thin films were wet-mixed and then deposited onto glass substrate by spin coating technique. The homogeneity distribution of anatase titania nanoparticles within amorphous silica matrix was evidenced by the results of X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FT-IR), and field emission scanning electron microscope (FE-SEM). The crystallite size of the mixed phase increased significantly upon increment of TiO 2 NPs content. The results of emission and photoluminescence excitation (PLE) confirmed the defects creation in the SiO 2 matrix. The trapped electrons and the presence of oxygen vacancies at the TiO 2 /SiO 2 interface enhanced the emission intensity of SiO 2 /TiO 2 nanocomposite thin films.
