Hybrid Plasmonic Surface Lattice Resonance Perovskite Lasers on Silver Nanoparticle Arrays

Abstract

The hybrid plasmonic surface lattice resonance (SLR) laser constructed by a MAPbBr3 perovskite thin film on the Ag nanoparticle array is unambiguously demonstrated in this research. The relatively high refractive index of the perovskite thin film provides an excellent coupling between the photonic mode and SLR, leading to a high spontaneous emission coupling factor and a low threshold lasing. Furthermore, a novel spin‐coating process applied to grow the MAPbBr3 perovskite thin film can leave air gaps under the perovskite that provides a large index difference in the periodic array, making the hybrid plasmonic SLR exhibits a high density of state, which is beneficial for laser operation. Via theoretical design and experimental verification, the lasing behaviors of the hybrid plasmonic SLR perovskite laser show excellent characteristics with a fixed polarization. This demonstration facilitates an enhanced lasing performance and realization of the low‐cost and low‐energy‐consumption laser application.

“…Another example of active hybrid 2D material SLRs is lasing. Recently, hybrid organic–inorganic metal–halide perovskite materials have become a popular low-cost platform for lasing gain materials due to their high photoluminescence quantum efficiency and wavelength tunability by changing the material composition. , Integrating thin-film perovskite with plasmonic arrays can lead to lasing by properly designing the array parameters and the thickness and material composition of perovskite film, as shown in Figure e.…”

“…For metal nanostructure arrays, other strategies involving far-field coupling, such as diffraction coupling in periodic arrays, have been widely employed. In this case, LSPRs couple with the in-plane Rayleigh anomalies (RAs), producing a narrow linewidth resonance pattern known as surface lattice resonance (SLR) [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. Since simple metal geometries do not support magnetic resonance, diffraction-coupled SLR observed in metal structures is mostly supported by electric dipoles/multipoles.…”

Directional Amplified Photoluminescence through Large-Area Perovskite-Based Metasurfaces

“…To introduce a periodic structural pattern into otherwise flat, continuous thin films of perovskite nanocrystals, the most straightforward method is through depositing the colloidal nanocrystals onto a prestructured substrate. This approach was previously successfully employed to generate enhanced directional PL, , manufacturing nanolasers, − photodetectors, and solar cells. , However, such an indirect patterning method lacks the possibility of creating more complex, multicomponent metasurfaces, provides suboptimal electromagnetic energy confinement, and relies on an elaborate substrate preparation . At the same time, direct patterning through ultraviolet (UV) or electron beam lithography (EBL) increases the risks of material degradation. − Some of these approaches have been explored for the patterning of metal halide perovskites, yet they present various challenges, including fabrication on a large scale and material degradation during processing. , A more appealing, low-cost, and scalable approach implies direct patterning of perovskite thin films through confinement self-assembly, where the colloidal solution of perovskite nanocrystals (or their precursors that are further turned into a solid crystalline phase) is confined on the substrate by a structured stamp. ,− As such, hard silicon (Si) stamps or glasslike molds were successfully employed to create structured metasurfaces with improved crystallinity , for modifying the emission properties ,,− and for photovoltaic applications. − However, the use of hard stamps requires additional surface modification and operation at high pressure and temperature.…”
