Control of optical processes in organometal halide perovskites using plasmonic nanoantennas — •Aurora Manzi, Lakshminarayana Polavarapu, Alexander Urban, and Jochen Feldmann — Chair for Photonics and Optoelectronics Ludwig- Maximilians-Universität (LMU), München, Germany
Fluorescence enhancement through the interaction of an emitting material with plasmonic nanostructures has been widely investigated for fluorophores ranging from dye-molecules to quantum dots for various applications. Plasmonic nanoparticles that are in the proximity of an emitting material change the local field and hence the absorption and photoluminescence characteristics of the material.
Perovskites are new materials that have recently attracted strong interest due to their fluorescence properties and possible applications in light emitting devices1. The interaction of perovskite nanocrystals with plasmonic structures could open new pathways for the application of such perovskite nanocrystals in various fields. However, there have not been many studies towards this direction.
In our studies we investigate the effect of plasmonic nanostructures on the photoluminescence of two-dimensional perovskite nanoplatelets. Bowtie nanoantennas were prepared with e-beam lithography and used as plasmonic resonators to study their influence on the optical properties of CH3NH3PbX3 (X=Br, I) platelets.
