Dynamic behaviors for light emission of one- and two-photon excitation in single crystalline perovskite bulks with metallic and dielectric-nanoparticles hybrid configurations are experimentally examined. Thereby, a series of comprehensive simulations are conducted for investigating the feasible mechanism and the relevant interactions in such sophisticated configurations. Under one-photon excitation, optical pumping fluences can only irradiate and penetrate in the skin depths of single crystalline perovskite-nanoparticle hybrid configurations; therefore, the corresponding light-emitting performance of hybrid configuration mixed with Au NPs can be ameliorated due to a stronger scattering field of Au NPs than that of SiO2 NPs. On the other hand, under two-photon excitation, optical pumping fluences can irradiate and penetrate much deeper; hence, the corresponding light-emitting performance of hybrid configurations mixed with both Au NPs and SiO2 NPs can be improved. However, owing to the shadowing effect of Au NPs, optical pumping fluences and the corresponding light-emitting in the interior regions will be shielded. Consequently, the overall light-emitting performance is slightly lower than that mixed with SiO2 NPs. We investigate the feasible mechanism in such sophisticated configurations and identify the relevant interactions between NPs and MAPbBr3 perovskite material, providing proper interpretations for a deeper understanding of the dynamic behaviors of one- and two-photon light emission in such single crystalline perovskite-nanoparticle hybrid configurations, paving a new route in nonlinear optics.
