Abstract
In this paper, a simple Tris (8-hydroxyquinolinato) aluminium (Alq3) /Ag particles/glass substrate trilayer structure was fabricated to investigate the metal-enhanced photoluminescence phenomena. The polystyrene sphere (PS) self-assembly technology was used to constitute nanoscale metallic particle array on the glass substrate. Based on the localized surface plasmons (LSPs) excited by these metallic particles, fluorescence enhancement of the organic light-emitting material has been actualized. The finite-difference time-domain (FDTD) simulations have been performed to analyze the experiment results. Subsequently, an optimized design which depended on the extinction cross-section of the metallic particles was proposed to improve the enhancement factor.
