Effect of Indium Tin Oxide (ITO) Nanoparticles on the Optical Properties Of PMMA Polymer

Abstract

In this work the optical properties of the PMMA polymer doped with different concentrations of ITO nanoparticles had been studied. All samples were prepared by casting technique with thickness of 1 mm. The optical properties ((absorption, transmission, absorption coefficient, extinction coefficient and refractive index) had been investigated. The doped composites have shown shifted toward the visible region. Whereas measured energy gap for pure and doped polymer shows decreases in the energy gap from 5.5eV to 3.5eV. The refractive index of pure polymer decreases as wavelength increase, where the refractive index of the doped polymer increases with increasing ITO concentrations.
