title = "Characterization of energy transfer processes occurring between pi-conjugated polymers and surface oxidized silicon nanoparticles",
abstract = "Electroluminescence (EL) from crystalline surface oxidized silicon nanoparticles (Si/SiO2 nps) randomly dispersed within Poly(9-Vinyl Carbazole) (PVK) was obtained. The energy transfer processes between the PVK polymer host and Si/SiO2 nps were investigated using intrinsic Poly(Fluorene)s (PFE). The PFE side chain lengths were selected to inhibit efficient energy transfer through direct carrier injection and Dexter processes by imposing a spatial separation between the polymer pi-conjugation and Si/SiO2 nps. Scalar EL emission, with no contribution from the Si/SiO2 nps, was observed from the three hybrid PFE(Si/SiO 2) devices implying no direct carrier injection, F{\"o}rster or Dexter energy transfer processes occur in the PFE hybrid devices. The Si/SiO2 np loads used were well below the percolation threshold, verifying the observed bulk dominated JV characteristics, which strongly suggest the observed Si/SiO2 np emission from the hybrid PVK device was produced by direct carrier injection.",
