Energy transfer dynamics in functionalised carbon nanotubes

Functionnalized NT are very promizing material for light harvesting applications since they combine the exceptionnal transport properties of carbon nanotubes and the versatility of organic dyes. In this study we show that a very strong interaction…

Quantum efficiency of energy transfer in noncovalent carbon nanotube/porphyrin compounds

We report on the quantum yield of excitation energy transfer in non-covalently bound nan- otube/porphyrin compounds. Evidence for energy transfer is gained from photoluminescence exci- tation experiments. We perform a quantitative evaluation of the…
