## Description

- description: '2D materials such as transition metal dichalcogenides (TMDCs) are
    a new class of atomic-layer materials possessing optical and electric properties
    that significantly depend on the number of layers. Electronic transitions can
    be manipulated in artificial resonant electromagnetic (EM) fields using metasurfaces
    and other designed nanostructures. Here, we demonstrate prominently resonant enhancement
    in the photoluminescence (PL) of atomic monolayer, WS$_2$, doped with a small
    quantity of Mo. The excitonic PL showed a strong enhancement effect on a higher-order
    magnetic resonance of all-dielectric metasurfaces consisting of periodic arrays
    of Si nanopellets. The PL intensity witnessed a 300-fold enhancement compared
    to the reference PL intensity on a flat silicon dioxide (SiO$_2$) layer, which
    suggests a drastic change in the dynamics of photoexcited states. Confocal PL
    microscopy and the analysis revealed that the single photons were efficiently
    emitted from the TMDC monolayer on the metasurface. Furthermore, examining the
    PL lifetime in the ps and ns timescales clarified two exponential components at
    the prominent exciton PL: a short-time component decaying in 22 ps and a long-time
    component lasting over 10 ns. Therefore, we can infer that the radiative components
    were significantly activated in the TMDC monolayer on the metasurfaces in comparison
    to the reference monolayer on a flat SiO$_2$ layer.'
