Abstract

The ultra-fast emission and nonlinear optical properties are reported in novel transition metal dendrimer nanocomposites. Time-resolved results show an ultra-fast decay for the gold (Au) and silver (Ag) dendrimer nanocomposites with a decay time of approximately 70 fs and a complex anisotropy decay result for the silver dendrimer nanocomposite. A weak decay result was obtained from the pristine PAMAM dendrimer and the emission spectrum is also reported. The wavelength dependence of the ultra-fast decay was also investigated for all systems. Nonlinear optical measurements were carried out with both gold and silver dendrimer metal nanocomposites. A strong nonlinear absorption effect was observed for the external configuration of the silver and gold dendrimer metal nanocomposites. The mechanism of the nonlinear absorption in this novel architecture is also investigated. These results show the potential of emission and nonlinear optical effects in a new architecture.
