Description
Summary:	Ferroelectric Polyvinylidene fluoride (PVDF) and its copolymers are used in a wide range of devices due to their excellent mechanical properties, high thermal and chemical stability, piezoelectric and pyroelectric responses. In the present investigation, Praseodymium oxide (Pr2O3) nanoparticles were synthesized hydrothermally and embedded in PVDF and films were fabricated by solution casting method. Enhancement of technologically important β-phase is observed in nanocomposite films. Electro active β and γ phase fractions are increased tremendously without poling and annealing is the highlight of the present work. Increased dielectric properties with low loss and enhanced photoluminescence on addition of nanoparticles are attributed to the enrichment of electro active phases.
