## Description

- description: Nanocomposite structures based on perovskite nanocrystals (NCs) and
    metal nanostructures within transparent monolithic media hold promise for a wide
    range of applications in optoelectronics. However, the microstructure of such
    nanocomposites and the reason for enhanced emissions remain incompletely understood.
    In this work, we present the successful creation of Ag-CsPbI3 nanocomposite within
    a highly transparent borosilicate glass (Ag-CsPbI3 NCs@glass). We reveal that
    Ag and CsPbI3 NCs form after thermal treatment of the glass, either in the form
    of Ag-CsPbI3 heterostructures or of separate Ag and CsPbI3 NCs. Based on combined
    characterization of Mott-Schottky and steady-state photoluminescence (PL) of the
    products, we attribute the enhanced PL in the nanocomposite of Ag-CsPbI3 to the
    regulation of CsPbI3 lattice by Ag ions and/or the plasmonic effect of Ag NCs.
    Temperature-dependent time-resolved PL measurements suggest that Ag NCs could
    play an important role in the relaxation process of excited carriers by increasing
    the radiative recombination. Moreover, the Ag-CsPbI3 nanocomposite structure within
    the glass matrix curtails PL quenching caused by water molecules and high temperature.
    Using the Ag-CsPbI3 nanocomposite, we achieve high-performance white light-emitting
    diodes with a color rendering index of 83.9 and luminous efficiency of 58.07 lmW-1.
    This work elucidates the underlying mechanism on the enhanced PL in nanocomposites
    containing perovskite NCs and metal nanostructures, and aids in the rational design
    of glass-based perovskite nanocomposites for a diversity of optoelectronic applications.
