Preparation of (PVA/Y2O3) Nanocomposite and Study the Optical Properties for Optoelectronic Device

Abstract

The casting method was used to investigated the (PVA) polymer and its doped with variant of weight percent of Y₂O₃ NPs. The morphological and optical properties was examined. The optical microscope (OM) denotes a good distribution of Y₂O₃ NPs, as well as charge transfer and form a network of paths within the polymeric matrix. The absorbance of (PVA/Y₂O₃) nanocomposite increases as the concentrations of (Y₂O₃) nanoparticles increase, whereas the transmittance and energy gap of (PVA/Y₂O₃) nanocomposite reduce with rise concentrations of (Y₂O₃) nanoparticles. The coefficient  of absorption, coefficient of extinction, index of refractive, real and imaginary parts of dielectric constants and conductivity  of optical are rising with the rise of the weight percentages of Y₂O₃ nanoparticles. the result indicate that this nanocomposite can be used for optoelectronic device.
