Synthesis and Applications of Large Heterometallic Cluster Systems

Abstract

Work has proceeded according to schedule on all research topics. Uniquely well defined clusters of Gold are now available for optical measurements. A comprehensive experimental investigation has been carried out to determine the non-linearity of these samples on a femtosecond timescale. These results are presented below and prove that: the nonlinear refractive index rises and relaxes on a sub-picosecond timescale, the nonlinearity is predominant positive imaginary originating from a hot electron contribution, the nonlinearity is independent of the size of the particle.
