title: Solid Confinement of Quantum Dots in ZIF-8 for Efficient and Stable Color-Conversion White LEDs.
abstract: The powder form and low photoluminescence quantum yield (PLQY) of fluorescent metal-organic frameworks (MOFs) present a serious obstacle to fabricating high-efficiency film-like lighting devices. Here, we present a facile way to produce thin films of CdSexS1-x/ZnS quantum dots (QDs)@ZIF-8 with high PLQY by encapsulating red, green, and blue CdSexS1-x/ZnS QDs in ZIF-8 through a one-pot solid-confinement conversion process. The QDs@ZIF-8 thin film emits warm white light with good color quality and presents good thermal stability and long-term durability.
