Polymer nanofluids of poly(vinylidene fluoride) (PVF₂) containing 0-5 wt % Ag nanoparticles (Ag NPs) are synthesized via a simple in situ caloric Ag⁺ ® Ag reaction in liquid N,N-dimethyl formamide by sonication in hot conditions. An upright dielectric field on formation of a percolation network over the electron donor Ag NPs and electron acceptor CF₂ from an ordered b-PVF₂ tailors light absorption 250-550 nm and green emission 520-620 nm of variable intensities, with a small percolation threshold of 0.1 wt % Ag NPs. On higher Ag contents, the intensity drops rapidly in both the absorption and emission roughly by an order of magnitude, following the percolation theory of a hybrid dielectric composite. Results open scope of developing newer materials for optical sensors, barcodes, energy transfer pairs, or light emitters.
