NANOSTRUCTURAL COMPOSITES OF PHTHALOCYANINE AND METALS

Thin composite films of metal nanoparticles incorporated into a phthal ocyanine matrix were prepared by simultaneous vacuum deposition of cop per and phthalocyanine from two evaporation sources. Absorption spectr a in both the IR and UV/VIS regions were measured in order to study ch anges of structure and properties with different volume fractions of c opper in the films. The effective medium theory (EMT) approach was use d to model optical spectra. A pronounced aging of composite layers was observed after the deposition.
