Dramatic fluorescence enhancement in two-dimensional (2D) van der Waals materials (vdWMs) coupled to plasmonic nanostructures has the potential to enable ultrathin
flexible
and high-brightness illumination devices. However
addressing the limitation of locally scattered small plasmon-enhanced areas remains challenging. Here
we present a 2D plasmonic enhancement of photoluminescence (PL) spanning nearly 800 μm
2
enabled by surface lattice resonance (SLR) in a 2D vdWM-Au slot lattice hybrid. The Au slot lattice is designed and fabricated using Babinet's principle and Rayleigh's anomaly to maximize radiative decay rate and induce non-local photo-excitation in a MoSe
2
monolayer. For emitted PL coupled with SLR
enhanced by up
to 32-fold
we investigate its in-plane directivity and long-range propagation using angle- and space-resolved spectroscopic PL measurements. Our experiment reveals that a nearly 800 μm
2
2D luminescent sheet can be achieved regardless of the size of the MoSe
2
crystal
even with a sub-μm
2
flake. This work provides a new type of ultrabright
large-area 2D luminescent material
suitable for a range of optical illumination
communication
and sensing devices.
