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 CdSe S /ZnS quantum dots (QDs)@ZIF-8 with high PLQY by encapsulating red, green, and blue CdSe S /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.
荧光金属有机框架材料（MOFs）的粉末形式和低光致发光量子产率（PLQY）严重阻碍了高效薄膜状照明器件的制造。在此，我们展示了一种简便的方法，通过一锅法固相限域转化过程将红色、绿色和蓝色的CdSe S/ZnS量子点（QDs）封装在ZIF-8中，从而制备出具有高PLQY的CdSe S/ZnS量子点@ZIF-8薄膜。该量子点@ZIF-8薄膜发出具有良好颜色质量的暖白光，并且具有良好的热稳定性和长期耐久性。
