Photothermal spectroscopy of dye-monolayer assemblies on solid substrates

Photothermal spectroscopy was employed to evaluate quantitatively the non- radiative de-excitation of cyanine dye monolayers organized on the water-air interface as J-aggregates and intercalated into Langmuir-Blodgett multilayer assemblies at various distances from a silver surface. © 1988.
