AI-generated Abstract

Polyvinyl alcohol (PVA) films doped with europium chloride (EuCl3) were synthesized, and their thermal and optical properties were characterized. The interaction of Eu3+ ions with PVA was investigated through FTIR spectroscopy. Results indicated increased Urbach energy and changing optical parameters with doping, demonstrating modified electronic transitions. Photocatalytic experiments revealed enhanced degradation of p-nitrophenol (PNP) with optimal activity at pH 5.5, making these composites promising for environmental applications.
