Fano effect of silver nanowire and perovskite nanoplatelets (NPLs). a Polarization of the biexciton shows the biexciton is along the Ag nanowire. b Plasmon resonant spectra of the nanogap shows a single symmetrical peak shown as a green dotted line. The plasmonic nanogap with perovskite NPLs shows a symmetrical peak. Red and blue dotted lines show the scattering spectra with parallel and vertical polarizations, respectively. c Finite-difference time-domain (FDTD) simulation results of b. The error bar corresponds to the standard deviation of the measurements
