Preparation and Study Optical Properties of (PVA-PVP-CrCl2) Composites

Raya Ali Abed, Majeed Ali Habeeb


In present research, the effect of addition chromium chloride (CrCl2) on the optical properties of (PVA-PVP) composite has been studied, samples have been prepared by adding (CrCl2) to poly vinyl alcohol and poly vinyl pyrrolidone with different weight percentages, the absorbance spectra was recorded in the wavelength range            (200-1100) nm. The absorption coefficient, optical energy gap of the indirect transition, extinction coefficient, refractive index and (real, imaginary) dielectric constant have been determined.

Keywords: Optical properties, (PVA-PVP) composites, chromium chloride.
