Polyvinylidene fluoride (PVDF) is employed in a wide range of devices based on its excellent mechanical, optical, high thermal, piezoelectric, pyroelectric, and ferroelectric characteristics. In the current investigation, the pristine and neodymium oxide (Nd 2 O 3 ) nanoparticles embedded polyvinylidene fluoride (PVDF) thick films were prepared via solution casting method. The Nd 2 O 3 nanoparticles were synthesized via hydrothermal technique. The functional groups were identified in the nanocomposite films via infrared vibrational spectroscopy. It revealed the presence of ferroelectric β-phase in the annealed nanocomposite films. All-important optical constants have been determined for the first time via UV-VIS transmission spectroscopy for the nanocomposite films in the ferroelectric phase.
