Organic–inorganic hybrid polyvinylidene fluoride–Co0.6Zn0.4Mn0.3Fe1.7O4 nanocomposite film with significant optical and magnetodielectric properties
Abstract
In this paper, we illustrate the significant optical and magnetodielectric properties of the polyvinylidene difluoride–Co0.6Zn0.4Mn0.3Fe1.7O4 nanocomposite film, containing the optimum weight content (0.5%) of CZFMO nanoparticles (average particle size ∼ 20 nm). The photoluminescence spectra of the nanocomposite film clearly demonstrated stable and sharp luminescence peaks at 430 nm (indigo region), 458 nm (blue region) and 490 nm (green region), accompanied by considerably higher intensity, compared to the broad emission peak (450–550 nm) observed for pristine polyvinylidene difluoride film. The results of fluorescence spectroscopy confirmed those obtained in photoluminescence. Polymer nanoparticle surface interaction could be the possible mechanism behind the enhanced optical properties. Additionally, this nanocomposite film exhibited frequency independent, linear and negative magnetodielectric effect ∼0.08% at the maximum applied field of 5 Tesla.
