Resonant Raman spectroscopy of PAH-Os self-assembled multilayers

A resonant Raman scattering and optical absorption study of self-assembled (PAH-Os/PVS)n and (PAH-Os/GOx)m multilayers was presented. It was found that a single monomolecular layer of PAH-Os deposited on a smooth gold surface shows resonant Raman scattering. The strong Raman resonance was observed a...
