Abstract
We have developed Pure Zinc Oxide (ZnO) and Pure Copper Oxide (CuO) and mixed Zinc-Copper oxide with five different ratios viz. 2-10gm, 4-10gm, 6-10gm, 8-10gm, 10-10gm in wt% by Sol-Gel technique then we have developed Pure PMMA and prepared Pure Zno, CuO and mixed Zinc-Copper oxide doped PMMA films by weight percentage of 9%. Prepared material doped PMMA composite films of thickness (∼100 μm) using the solution-cast technique. To spot the possible change that happen to the PMMA films as a result of doping, the optical properties were investigated for various wt.% ratios of Zinc, Copper, mixed Zinc-Copper oxide materials by recording the absorbance and transmittance spectra of those films using EI2375 double beam UV–Vis spectrophotometer within the wavelength range of 300–1100 nm. From the info obtained from the optical parameters viz. coefficient of absorption, extinction coefficient, finesse coefficient, refractive index, real and imaginary parts of dielectric constant and optical conductivity were calculated for the prepared films. The indirect optical band gap for the pure and therefore the doped-PMMA films were also calculated.
