Optically Nonlinear Langmuir-Blodgett-Films - Influence Of The Substrate On Film Structure And Linear Optical-Properties

Normal incidence transmission measurements and surface plasmon spectroscopy at optical frequencies are used to probe the optical and structural properties of an optically nonlinear dye, deposited onto glass and silver substrates by the Langmuir–Blodgett technique. The particular orientation and proximity to the silver surface afforded by the deposition method reveals strong molecule/metal interactions hitherto unreported for LB film assemblies on silver.
