PVA/Gd2O3@Zno Nanocomposite Films as New Uv-Blockers: Structure and Optical Revelations
Herein we have synthesised Gadolinium oxide doped Zinc oxide (Gd 2 O 3 @ZnO) by solution combustion method and incorporated it as a nano-filler into Polyvinyl alcohol (PVA) polymer matrix using solution intercalation technique to get PVA/Gd 2 O 3 @ZnO nanocomposite film. The X-ray diffraction (XRD),...

@ZnO film shows the interaction of –OH groups in PVA and dopant. From DSC, it is clear that Tg of prepared nano-composites increases with increasing in dopant concentration. XRD analysis showed that the crystalline characteristics of the nanocomposites increases with increase in dopant concentration. The UV–Visible spectra reveals that there is decrease in indirect band gap of PVA from 4.94 to 3.12 eV and direct band gap from 4.90 to 3.03 eV compared to pristine PVA Gd
