Fِrster resonance energy transfer from poly(9-vinyl carbazole) to silicon nanoparticles in their composite films

A novel organic–inorganic hybrid composite was prepared from poly(9-vinyl carbazole) (PVK) and silicon nanoparticles (NPs). The optical properties of the composites were characterized by photoluminescence (PL), photoluminescence excitation (PLE), and PL decays. The results indicated that an efficient Förster resonance energy transfer (FRET) took place from PVK (donor) to silicon NPs (acceptor), which was necessary for the optimization of polymer/inorganic NPs hybrid light-emitting diodes.
