Au-Polaritons Regulated Molecular Dipoles on Empowering the Giant Pyroelectric Response of Highly Oriented Dipoles of PVDF Thin Films

Ferroelectric polymers reinforced with noble metals enable advanced sensors, photodetectors, flexible electronics, and energy harvesters. This study investigates the effects of integrating hexagonal nanogold (n-Au) into poly(vinylidene fluoride) (PVDF), a prominent ferroelectric polymer, to advance the structure-property relationship in hybrid materials for next-generation sensor and energy conversion technologies. The fabricated Au-PVDF thin films (<= 100…

Highly Stable Photoluminescence in Vacuum-Processed Halide Perovskite Core–Shell 1D Nanostructures

Hybrid organometal halide perovskites (HP) present exceptional optoelectronic properties, but their poor long-term stability is a major bottleneck for their commercialization. Herein, a solvent-free approach to growing single-crystal organic nanowires (ONW) is presented, along with nanoporous metal oxide scaffolds and HP, to form a core@multishell architecture. The synthesis is carried out under mild vacuum conditions…
