Plasmonic Enhanced Electroluminescence from Light-Emitting Electrochemical Cells

Abstract

Solid-state light-emitting electrochemical cells (LECs) have received intense scientific attention since they show advantages of simple device structure, low-voltage operation and compatibility with air-stable electrode metals. To further improve device performance, enhanced electroluminescence (EL) from localized surface plasmon resonance in LECs incorporating gold nanourchins (NUs) at the anode is demonstrated. With gold NUs, peak device efficiency of LECs can be enhanced by 35%. The proposed technique is a simple and feasible way to improve device performance of LECs.
