Effect of Doping Ratios of Rhodamine6G Dye on Optical Properties and FT-IR Spectroscopy of Polyvinyl Acetate Polymer

Abstract

Optical properties such as absorption coefficient, refractive index, and
extinction coefficients of pure polyvinylacetate (PVAc) and Rhodamine6G
(Rh6G) laser dye doped with PVAc thin films where prepared using casting
method, in order to study the effect of Rhodamine 6G additions on the optical
properties of (PVAc) hosts.
These films were described using UV/VIS technique in order to assessment the
type of transition which was found to be indirect transition.
Fourier Transform infrared (FT-IR) spectroscopy was used to identify the effect
of (Rh6G) on the characteristic functional groups of PVAc.
