Abstract

This paper is intended to demonstrate the effect of surface plasmon coupled emission (SPGCE) on the plasmonic response of lamellar grating in both Au-grating/Alq₃ and PR-grating/Alq₃ nanostructures. Recently, intriguing studies on an appropriate nanostructure of the corrugation allows the non-radiative SPP mode to be coupled out as light into the far field with direction determined by the grating diffraction condition. It has also been shown that surface plasmon coupled emissions (SPCE) from fluorescent molecules by incident wave excite an evanescent field near the periodic metallic structure, Kretschmann configuration and multilayer grating structure to increase the radiation efficiency. In this paper, we propose to use this technique of SPGCE has performed on the localized surface plasmon (LSP) and surface plasmon band gap (SPBG) characteristics of the lamellar grating nanostructure.
