Effect of (FeSO4 ) Doping on Optical Properties of PVA and PMMA Films
Abstract
Films of pure PVA , PMMA and PVA, PMMA doped by (FeSO4) have been prepared using casting method. Transmission and absorption spectra have been recorded in the wavelength range (300-900) nm. the study of the optical properties of the deposited films have done in order to identify the possible change that happen to the PVA, PMMA films due to doping. Optical constants like refractive index , extinction coefficient calculated and correlated with doping.
Keywords: PVA,PMMA , casting method, optical properties, Effect of (FeSO4 ) Doping.
