Plasmonic nanoparticles boost low-current perovskite LEDs governed by photon recycling effects.

ABSTRACT: Perovskite light-emitting diodes (PeLEDs) have emerged as a promising technology for next-generation display and lighting applications, thanks to their remarkable colour purity, tunability, and ease of fabrication. In this work, we explore the incorporation of plasmonic spherical nanoparticles (NPs) directly embedded into the green-emitting CsPbBr₃ perovskite layer in a PeLED as a strategy to enhance both its optical and electrical properties. We find that plasmonic effects directly boost spontaneous emission while also influencing charge carrier recombination dynamics. We present a rigorous theoretical electro-optical analysis to systematically investigate the impact of NP metal, size, and concentration on device performance, with particular emphasis on the role of photon recyc
