Transparent thin films based on nanocomposites of BaTiO3, (PMMA) and poly (4-vinylphenol) (PVP) are synthesized and deposited on fluorine doped tin oxide (FTO) coated glass substrate by spin coating technique. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) are applied to investigate the chemical bonds and structural properties of the samples. The optical transmittance and reflectance of nanocomposite films are investigated in the 200–900 nm wavelength range. The calculation of optical band gaps of thin films showed that the thin film has directly allowed transition with the values from 3.3 eV to 3.4 eV. Dispersion parameters are calculated based on the single oscillator model. The important parameters such as dispersion energy, oscillator energy and lattice dielectric constant are extracted for thin film. The electrical properties such as capacitance and electrical behavior are investigated for sample. The obtained results of nanocomposite thin films can be useful for using in transparent organic thin film transistor.
