## Description

- description: "Embedding halide perovskite nanoparticles (NPs) into glasses can be
    regarded as a feasible approach to improve their long-term stability when they
    are exposed to air or moisture. However, it remains elusive to rationally grow
    highly luminescent halide perovskite NPs owing to poor understanding of the relationship
    between glass network topology and NP precipitation. Here, by introducing alkali
    metal ions as “B-phase structural scissors”, the precipitation and aggregation
    of NPs are optimized based on glass network topology modulation, which boosts
    their photoluminescence performance. After Li doping, the photoluminescence quantum
    yield of CsPbBr3 perovskite NPs embedded in glass increases by 39% with respect
    to that of the undoped counterpart. The alkali metal ions are utilized to reduce
    thermal activation energy from 130.04\r\nKJ mol−1 to 125.35 KJ mol−1 according
    to thermodynamics analysis, which corresponds to an increase in the size of the
    NPs. Benefiting from excellent chemical inertness, the luminescence intensity
    of as-made CsPbBr3 NP embedded glass retains near unity after soaking them in
    water for 180 days. The utilization of alkali metals as a facile strategy to modify
    the glass network enables improved performance of target NPs, thereby providing
    deeper insights into the design of host-dependent NP-functionalized glass."
