Abstract

Silver was evaporated on Langmuir-Blodgett (LB) films of cadmium arachidate and phthalocyaninato-polysiloxane. Electron microscopy and UV-visible- near IR absorption spectroscopy show that the island formation and the sticking probability of silver depend on the thickness of the cadmium arachidate films. The surface coverage and sticking probability of silver on the polymeric phthalocyanine is considerably higher on and independent of the LB film thickness. A qualitative explanation is based on the different film structures and morphologies. Therefore the evaporation of silver on various surfaces and the formation of metal islands with their characteristic optical absorptions can be used to visualize different surface properties.
