Synthesis and Study of Optical Properties for (4-Acetyl aminophenol –[2-(4-Azo)]-4-Aminodiphenyl Sulfonate) (AAS):Polyvinylpyrrolidone (PVP) by Film Preparation on Quartz Substrate

Abstract

New azo dye was prepared from 4,4-diaminodiphenyl sulfonate with 4-Acetyl aminophenol. The dye prepared by fox method, the azo dye were identified by IR–spectrophotometer and (CHN) analysis. Polyvinylpyrrolidone films of thickness 32 μm was prepared onto quartz substrate. The optical constants of the film were investigated by spectrophotometric measurement. The refractive index, extinction coffesiont and optical band gap (Eg ) are determined using the transmittance (T) and reflectance (R) in the spectra wavelength (340-700) nm
