Abstract
Surface plasmon (SP) emission light has been investigated for rhodamine-B (RB) dye Langmuir-Blodgett (LB) films on silver (Ag) thin film in the attenuated total reflection (ATR) Kretschmann configuration by means of reverse irradiation of a laser beam. Emission light through the prism was clearly observed for the configuration of prism/Ag/LB films corresponding to the resonant excitation conditions for SPs using the reverse irradiation. The intensities of the SP emission light increased with the thickness of the RB LB films, but nonlinear reductions of the SP emission light and photoluminescence (PL) were observed due to nonradiative energy transfer at the very small separations between the RB and Ag films. It is thought that the SPs, that is, two-dimensional optical waves, are excited by PL of the RB dyes on the Ag film and that this phenomenon is very useful for applications utilizing dye molecules on metal thin films.
