## Description

- description: 'Transition metal dichalcogenides (TMDC) are a family of atomic-layer
    two-dimensional materials (2dMs). Many researches have attempted to reinforce
    the unique properties by incorporating artificially designed nanostructures. Here,
    a highly photoluminescence (PL) enhancing platform is reported that was formed
    by combining high-emittance plasmo--photonic metasurfaces with a large-area 2dM,
    which was a continuous monolayer of TMDC of cm<sup>2</sup> dimension. It is experimentally
    demonstrated that the 2dM-PL intensity at room temperature was enhanced by more
    than 1030-fold in comparison with that observed on the flat gold film regions.
    The enhancement is associated with spectral transformation indicating a resonant
    effect of the metasurfaces. It is moreover revealed that the confocal PL image
    originates from a coherent single-mode emission that forms a photon number distribution
    obeying the Poisson probability distribution. Thus, the 2dM-fused metasurfaces
    function as efficient coherent quantum light sources. PL decay-time analysis also
    reveals the coexistence of two components in the enhanced PL. The fast component
    exhibits a lifetime of 18 ps whereas the slow component decays at 4.4 ns. Both
    components are most likely to undergo radiative processes, which indicates that
    metal-induced PL quenching is suppressed on these 2dM-fused metasurfaces. The
    long lifetime component is ascribed to an excitonic intervalley transition. '
