Enhanced Optical Properties of PVA–CuO–Fe2O3 Nanocomposites for Optoelectronics Applications

The current work aims to fabrication of nanocomposites' films of CuO-Fe 2 O 3 -nanoparticles'-doped PVA to apply in many optoelectronics applications.The PVA-CuO-Fe 2 O 3 nanocomposites are prepared using casting method.The optical properties are tested at wavelength range from 200 nm to 800 nm.The results show that the absorbance and absorption coefficient of PVA is increased with increasing CuO-Fe 2 O 3 -nanoparticles' ratio.The transmittance and energy gap of PVA is reduced with increasing CuO-Fe 2 O 3 -nanoparticles' ratio.The obtained results confirm that the PVA-CuO-Fe 2 O 3 nanocomposites can be important for optoelectronics fields.
