Surface lattice resonances (SLR) is a hybrid plasmonic-photonic resonance supported on nanoparticle arrays that provides strong and directional photoluminescence enhancement (PLE) via Purcell effect and directional out-coupling. We analyzed the Purcell effect mediated by SLR and propose an analytical model that predicts the PLE with parameters that can be obtained through spectral measurements. We studied a wide variety of structures in both numerical simulations and experiments to verify the predictive power of the model.
