## Description

- description: All-inorganic cesium lead halide perovskite quantum dots (QDs) have
    emerged as promising materials for next-generation optoelectronic devices due
    to their exceptional photoluminescence (PL) properties, including high quantum
    yields and narrow emission line widths. However, unlocking their full potential
    requires innovative strategies to further enhance and precisely tune their fluorescence
    efficiency. In this work, we present a novel 0D-2D-3D mixed-dimensional van der
    Waals (vdW) heterostructure comprising CsPbBr3 QDs, multilayer hexagonal boron
    nitride (hBN), and a gold (Au) nanoparticle film, achieving a remarkable 7-fold
    PL enhancement. We attribute this enhancement to the synergy of plasmon-induced
    enhancement of the incident electromagnetic field and an increased spontaneous
    emission rate via the Purcell effect, optimized by tuning the hBN spacer thickness
    to 26 nm. This heterostructure design provides new insights into metal-enhanced
    photoluminescence for perovskite quantum dots, and it offers a scalable platform
    to enhance efficiency in future optoelectronic applications.
