“…Moreover, MO NPs are well known to possess attractive properties such as stiffness, transparency, good thermal and chemical stabilities. Nanocomposites synthesized by blending polymers with MO NPs exhibit properties of both components to yield multifunctional materials with new or enhanced properties overtaking each single-component independently [ 11 , 12 , 13 , 14 , 15 ]. Recently, considerable interest has been focused on nanocomposite thin films due to their physical properties and applications in optical lenses, UV shielding, light emitting diodes (LED), photo-detectors, solar cells, multi-sensors, organic transformation reactions, super capacitors and corrosion protections [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ].…”

The study focusses on synthesis and modification of structural, optical and electrical characteristics of nanostructured titanium dioxide anatase embedded Poly(methyl methacrylate) (PMMA) nanocomposite with different weight percentages (0.03, 0.06, 0.12, 0.18 and 0.24%) by the solvent casting method. Modification in the morphology of PMMA nanocomposites with an increasing amount of titanium dioxide anatase is studied by using a field emission scanning electron microscope (FE-SEM). Micrograms of FE-SEM show spherical shaped nanoparticles distribution in PMMA nanocomposites thin films. In optical characterization, transmission, optical band gaps, the real and imaginary part of dielectric constant, linear susceptibility, optical conductivity, refractive index and extinction coefficient are calculated using experimental data. It is observed that the optical band gap has an overall decreasing trend with increasing the weight percentage of TiO 2 (anatase) in PMMA nanocomposites. It is also found that values of all electrical parameters decrease with increasing the weight percentage of TiO 2 (anatase) in PMMA nanocomposites. All wavelength depending parameters are investigated in the wavelength range from 190 nm to 2700 nm. Single oscillator model is used to analyze the refractive index dispersion and estimation of the oscillator energy and dispersion energy of the films. The study is applicable to optical sensors and other optoelectronic devices.

The influence of film thickness on the structural and optical properties of silicon dioxide (SiO2) and zinc oxides (ZnO) thin films deposited by radio frequency magnetron sputtering on quartz substrates was investigated. Deposition conditions were optimized to achieve stoichiometric thin films. The orientation of crystallites, structure and composition were investigated by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), while the surface topography of samples was analyzed using scanning electron microscopy (SEM). The optical characteristics were measured for samples with the same composition but obtained with different deposition parameters, such as increasing thickness. Optical constants (i.e. refractive index n, extinction coefficient k, and absorption coefficient α) of the SiO2 and ZnO oxide films were determined using Swanepoel’s method from the transmission spectra recorded in the range 190 - 2500 nm, while the energy bandgap was calculated from the absorption spectra. The influence of thickness on the structural and optical properties of the oxide films was investigated. A good optical quality and real performance was noticed, which makes these thin films deem worthy of integration into metamaterial structures.
