On the other hand, halide perovskites are known to possess high refractive index, and they support excitons at room temperature with high binding energies and quantum yield of luminescence that makes them very attractive for all-dielectric resonant nanophotonics. Here we employ halide perovskites to create light-emitting nanoantennas with enhanced photoluminescence due to the coupling of their excitons to dipolar and multipolar Mie resonances. We demonstrate that the halide perovskite nanoantennas can emit light in the range of 530-770 nm depending on their composition. We employ a simple technique based on laser ablation of thin films prepared by wet-chemistry methods as a novel cost-effective approach for the fabrication of resonant perovskite nanostructures.This work was supported by the Ministry of Education and Science of the Russian Federation (Project 14.Y26.31.0010 for optical measurements), Russian Science Foundation (Project 17-73-20336 for calculations), and the Australian Research Councilapplication/pdfen-AU© 2018 American Chemical SocietyHalide perovskitesphotoluminescencenanoantennaMie resonancePurcell effect201810.1021/acs.nanolett.7b047272020-11-23
