Enhancement of Optical Parameters for PVA/PEG/Cr2O3 Nanocomposites for Photonics Fields

In this study, many samples have been synthesized by using solution casting technique with different additive content of Chromium oxide nanoparticle (Cr2O3NPs), poly vinylalcohol (PVA) and polyethylene glycol (PEG). The UV-Vis. spectrophotometer used to record the absorbance spectrum in range (200-800) nm. absorption UV waves is improved while transmittance reduced when Cr2O3 NPs were added polymeric system which are useful for a number applications including low-cost protection solar radiation shield. When concentrations increased, optical energy gap indirect transition (allowed forbidden) was decreased. Furthermore, all constant has improved.
