We present data on the NIR/VIS/UV optical constants of thin composite
layers, built up from a copper phthalocyanine matrix with embedded met
al clusters. The metal clusters (copper, gold and silver) have diamete
rs on a nanometre scale and act as strong absorption centres. In parti
cular, local plasmon resonances and metal interband transitions could
be observed from a fit of the experimentally determined dielectric fun
ctions by means of a Lorentzian multi-oscillator model. Average dipole
transition matrix elements with respect to a single metal cluster hav
e been estimated from the oscillator parameters.
