Abstract

The research focuses on polymeric composites made of PVA doped with ZnO, MoO₃, and Fe₃(PO₄)₂·8H₂O. Furthermore, a shifting in absorption edge for PVA was observed in UV experiments; it begins at 3.5 eV and reduces to 2.6 eV for PVA-ZnO composite. The indirect band gap lowers for all compositions, filled by ZnO/MoO₃/ Fe₃(PO₄)₂.8H₂O, and it reaches 2.6 eV for PVA-ZnO composite. On the other hand, the refractive index of PVA is 1.687, while in PVA-ZnO-MoO₃-Fe₃(PO₄)₂.8H₂O composite, it is 2.03. Furthermore, after doping with MoO₃ and Fe₃(PO₄)₂.8H₂O, the dielectric constant for PVA decreased from roughly 28 to less than 20 and increased to about 47 in PVA-ZnO composite. The dielectric and optical investigation of PVA/ZnO/MoO₃/Fe₃(PO₄)₂.8H₂O composites demonstrated the importance of their characterization in optoelectronic applications.
