Аннотация
PVA films that have been cast with and without carboxymethyl cellulose (CMC) doping. In order to study optical constants such as refractive index, real and imaginary parts of the dielectric constant, these additives affect all the parameters under study and increase their value especially the optical absorption, the absorbance and transmittance spectra have been recorded for all the deposited films. The absorption coefficient numbers refer towards the permitted direct transition.
