Tunable RF-Responsive Core-Shell Organofullerenyl-Magnetic Hybrid Nanostructures as Multiferroic Nanomaterials
Abstract
A sequential synthetic method to fabricate multilayered hybrid nanostructures on either -FeOx@AuNP nanoparticles or sandwiched graphene sheets with measurements of reversible and photoswitchable dielectric property amplification characteristics was performed at 1.04.0 GHz. Six variable organic electron donors and two conducting conjugated polymers were also applied to serve as the supply of photoinduced transferrable electrons at the outer shell layer. The design largely increased the number of polarizable charges, leading to a maximum of 387% amplification of the relative dielectric constant (r) value. Good recyclability of r back to their original values during each photoactivation cycle of light-on and light-off manipulations may allow the potential uses as dielectrics in photoswitchable modulation of RF reflection signals. In the case of graphene samples, large further increase of reversible dielectric permittivity r amplification of 308% by photoexcitation at the plasmonic gold shell layer using a white LED light was achieved.
