Enhancing perovskite film fluorescence by simultaneous near- and far-field effects of gold nanoparticles

Abstract

In this work gold nanoparticles (Au NPs) are incorporated into a PEDOT:PSS layer, resulting in ∼4.0 fold enhanced fluorescence emission of a CH3NH3PbBr3 film. Through experiments and theoretical simulation, we first demonstrated that the enhancement comes from the simultaneous near- and far-field effects of Au NP enhanced perovskite fluorescence.
