A facile strategy to encapsulate R-phycoerythrin (R-PE) proteins and CdSexS1−x/ZnS quantum dots (QDs) in ZIF-8 thin films is developed through a one-pot solid-confinement conversion process. The resultant R-PE/CdSexS1−x/ZnS@ZIF-8 thin film exhibits high-quality white light emission and good thermal stability up to 80 °C.
