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

الملخص EN

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 ???? was prepared onto quartz substrate.

The optical constants of the film were investigated by spectrophotometric measurement.

The refractive index, extinction coffesiontand optical band gap (Eg) are determined using the transmittance (T) and reflectance (R) in the spectra wavelength (340-700) nm.
