Abstract

Emission light through a prism has been investigated for prism/silver (Ag) thin film/merocyanine (MC) Langmuir-Blodgett (LB) films in the Kretschmann configuration. Emission light was observed by means of direct irradiation of a laser beam from air to the MC LB films, that is, reverse irradiation. The emission properties coincided with resonant conditions of surface plasmon (SP) excitations in the Kretschmann configuration. Emission due to SP excitations depended upon the position of the MC LB film in the LB hetero films of arachidic acid (C20)/MC/C20 on the Ag thin film. The strongest emission was observed at some separation of the MC LB layer from the metal surface. Emission properties were also investigated for the hetero LB films of MC and C20 on aluminum (Al) thin film and for the MC LB films with various thicknesses. It is thought that the phenomenon is useful for application to new devices utilizing multiple SP excitations.
