Abstract

Cesium lead halide perovskite nanocrystals show great promise for optoelectronic applications due to their thermal stability, wide absorption range, and intense photoluminescence. These properties make CsPbX 3 (X = Cl, Br, or I) nanocrystals great potential candidates for incorporation into light harvesting antenna complexes and photon multipliers via the coordination of organic chromophores as surface-bound ligands. In this paper, we demonstrate the synthesis of CsPbBr 3 and CsPbI 3 NCs and direct in situ attachment of anthracene-9-carboxylic acid ligands to their surface. Using steady-state and time-resolved fluorescence measurements, we show that CsPbX 3 –anthracene systems demonstrate energy transfer from the anthracene ligands via FRET with efficiencies as high as 40%.
