摘要：

This work investigates the structure, morphology, and optical properties of TiO2 nanoparticles embedded in a Fe2O3-PVA composite matrix. The samples were examined using a variety of techniques, including field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), absorption and transmission spectra, and Fourier transformation infrared (FTIR). Crystallography information revealed the presence of TiO2 doesn't effect in the crystal structure of PVA-Fe2O3. The manufactured composites demonstration strong absorption in the range of 440-570 nm. It is important that the highest absorption of these composites gradually shifted to the shorter wavelength region with presence of TiO2. PVA-Fe2O3 is highly transparent with transmittance of around 85 % in range 600-800 nm. After addition of 2.5 % by weight of TiO2 nanoparticles, the transmittance of nanocomposite drops to 75% in the same range of wavelength. Further addition of nanoparticles reduced the percentage transmittance to 68%. The results specify that as the TiO2 ratio increases, the band gap be wider.
