Article Synopsis
- Researchers studied how composite films made of a semiconducting polymer (PPV) and single-walled carbon nanotubes (SWNT) work, focusing on their light-related properties up to a 64% nanotube concentration.
- They used photoexcitation techniques and density functional theory to explore these mechanisms.
- The experiments showed that when SWNTs are present, PPV's light emission decreases quickly, indicating charge separation, especially at low SWNT concentrations, and the calculations suggested strong electronic interactions between the polymer and the nanotube network when the nanotubes are semiconducting.
We report a general and simple approach to take control of the color of light-emitting two-luminophore hybrid nanowires (NWs). Our strategy is based on the spatial control at the nanoscale (coaxial geometry) and the spectral selection of the two kinds of luminophores in order to restrict complex charge and energy transfers. Thus, it is possible to control the color of the photoluminescence (PL) as an interpolation of the CIE (Commission Internationale de l'Eclairage) coordinates of each luminophore.
