Abstract:
This study scrutinizes the susceptibility of the optical properties of polyvinyl alcohol (PVA)-Polyethylene glycol (PEG) blend to the addition of manganese dioxide (MnO2) nanoparticles with 0, 1.8, 3.6, and 5.4 wt. %. Then, the casting method was applied to produce the final nanocomposite films that subjected to a wavelength range from 200 nm to 800 nm to record the absorption spectrum. Hence, we have measured the absorption coefficient, extinction coefficient, allowed indirect energy gap, forbidden transition, real dielectric constant, and imaginary dielectric constant. The main outcome is that there is an increase in the optical constants with the increasing weight ratio of MnO2 nanoparticles. However, the calculated energy gap was observed it decrease with the increasing of the percentage weight of MnO2 nanoparticle.
