Abstract
We report the results of ultra-fast fluorescence investigations from gold-dendrimer nanocomposites of different morphologies. Femtosecond depolarized emission has been detected and characterized for Polyamidoamine (PAMAM) G5-based gold colloids, which possess a complex architecture. This is in contrast to the result for G9 PAMAM dendrimers in which one gold nanoparticle of near spherical shape is formed in one dendrimer molecule. For this larger structure no detectable ultrafast emission was observed. The local field enhancement effect is discussed in regards to the observed morphology dependence.Citation
