## Description

- description: "Solution-processed metal halide perovskite nanocrystals (NCs) have
    emerged as exceptional emitters for next-generation optoelectronics and nanophotonics,
    owing to their high photoluminescence quantum yields and tunable optical properties.
    However, coupling these colloidal nanomaterials with complex photonic resonators
    faces severe limitations, particularly on suspended structures where capillary
    infiltration disrupts film continuity, fundamentally hindering efficient light-matter
    interaction. Here, we introduce a graphene-scaffolding strategy that overcomes
    these limitations, enabling the deterministic fabrication of a continuous, ultrathin
    (~28 nm) CsPbBr3 NC film on freestanding photonic membranes. The atomically thin
    graphene interface effectively bridges air holes, preventing nanomaterial infiltration
    and suppressing scattering losses. This architecture provides an ideal nanophotonic
    platform to exploit engineered\r\ndual-mode non-hybridizing bound states in the
    continuum. By aligning orthogonal resonances for field superposition, we achieve
    giant energy localization and a record-high (~200-fold) photoluminescence enhancement.
    This work highlights 2D-material scaffolding as a universal interface for integrating
    solution-processed nanomaterials with advanced nanophotonic\r\narchitectures."
