Optical Properties of Polyvinylpyrrolidone (PVP) Films Doped with Nickel Nitrate (NiNO3)
Abstract: The pure of polyvinylpyrrolidone (PVP) and PVP-NiNO3 composite with different weight percentage of NiNO3 were prepared using casting technique. the optical properties of all samples were studied in the room temperature by using UV-VIS/160/Shimadzu spectrophotometer at (200-800) nm wavelength region. The effect of NiNO3 concentration on the optical properties of (PVP- NiNO3) composites have been investigated. The experimental results show that the samples have indirect transition. the energy band gap decrease with increase the concentration of NiNO3. The optical constants (Refractive index, Extinction coefficient, Real and Imaginary parts of the dielectric constant) showed clear changes with increasing the doping concentrations.
