Abstract

Samples are described which consist of coagulated quasi-fractal structures of 20 nm goldparticles embedded in a nonconducting matrix. By varying coagulation into coalescence electrical percolation can be induced while all topological parameters are kept constant. The first steps of percolation were investigated from the optical spectra. From calculations a fundamental limit for the splitting of plasmon modes in coagulation aggregates of arbitrary size and shape was found. In coalescence aggregates this limit is markedly surpassed. The percolation correlation length can be estimated therefrom. In the present case it amounts to about 300 nm.
