Influence of Titanium Oxide on Properties of (Fe2O3-Sb2O3) Nanocomposites for Renewable Energy and Electronics Applications

The Fe2O3-Sb2O3TiO2 nanoceramics thin films were synthesized by using spray pyrolysis method. The spray pyrolysis method is simple technique, low cost and high quality to prepare the nanocomposites. The (Fe2O3-Sb2O3) nanopowders were used with concentration 1:1. The (Fe2O3-Sb2O3) nanocomposites were prepared with concentrations are 0.01 g/20 ml, 0.02 g/20 ml, 0.03 g/20 ml, 0.04 g/20 ml of distilled water. The TiO2 nanoparticles were added to (Fe2O3-Sb2O3) nanocomposites with weight percentage 20 wt%. The samples of (Fe2O3-Sb2O3-TiO2) nanocomposites were fabricated with concentrations are 0.01 g/20 ml, 0.02 g/20 ml, 0.03 g/20 ml, 0.04 g/20 ml. The (Fe2O3-Sb2O3-TiO2) nanocomposites were prepared with thickness 250 nm. The structural and optical properties of (Fe2O3-Sb2O3-TiO2) nanocomposites were studied. The structural properties were measured by using optical microscope. The optical properties were studied in wavelength range (300-800) nm by using UV/1800/Shimadzu spectrophotometer. The experimental results showed that the optical absorbance and conductivity of (Fe2O3-Sb2O3) thin films increase with increase in TiO2 nanoparticles concentrations. The energy band gap of (Fe2O3-Sb2O3) decreases as TiO2 nanoparticles concentrations increase. From the results, the (Fe2O3-Sb2O3-TiO2) nanocomposites may be used in different fields for renewable energy and optoelectronics applications.
