Issue Date: | 2023 | Publisher: | ROYAL SOC CHEMISTRY | Source: | Nanoscale Advances, 5 (6) , p. 1750 -1759 | Abstract: | Enhancement of the spontaneous emission of fluorophores aided by plasmonic nanoparticles (PNPs) prompts the growth of plasmonic organic light emitting diodes (OLEDs). Together with the spatial dependence of the fluorophore and PNPs on enhanced fluorescence, the surface coverage of the PNPs controls the charge transport in OLEDs. Hence, here, the spatial and surface coverage reliance of plasmonic gold nanoparticles is controlled by a roll-to-roll compatible ultrasonic spray coating technique. A 2-fold enhancement in the multi photon fluorescence is seen by two-photon fluorescence microscopy for a polystyrene sulfonate (PSS) stabilized gold nanoparticle located 10 nm away from the super yellow fluorophore. Fluorescence enhancement combined with similar to 2% surface coverage of PNPs, provides a 33%, 20% and similar to 40% increase in the electroluminescence, luminous efficacy and external quantum efficiency, respectively. | Notes: | Kumar, RSN; Deferme, W (corresponding author), UHasselt Hasselt Univ, Inst Mat Res IMO IMOMEC, Agoralaan 1, B-3590 Diepenbeek, Belgium.; Kumar, RSN; Deferme, W (corresponding author), IMEC, IMOMEC Div, Wetenschapspark 1, B-3590 Diepenbeek, Belgium. rachith.shanivarasanthe@uhasselt.be; wim.deferme@uhasselt.be |
