Abstract： Fluorescent nanodiamonds （FNDs） containing nitrogen vacancy （NV） centers exhibit broad prospects in quantum sensing， quantum computing， and fluorescence imaging due to their unique properties. Functionalizing FNDs with ordered porous metal-organic frameworks （MOFs） provides a controlled environment for quantum applications. This approach facilitates the immobilization of FNDs and enhances their interactions with other substances on their surface. This study explores a composite material of FNDs and MOFs. By encapsulating FNDs within the biocompatible metal organic framework zeolite imidazolate framework-8 （ZIF-8）， the fluorescence and quantum sensing performance of FNDs were effectively preserved， and selective encapsulation by ZIF-8 resulted in observable changes in the fluorescence lifetime of FNDs. Furthermore， the study investigates the modulation effects of different synthesis conditionson the size and morphology of FNDs@ZIF-8. Through an in-depth exploration of FNDs@MOFs composite materials， the research unveils the quantum characteristics of FNDs within the composite， offering new avenues for designing more flexible， high-performance fluorescence imaging devices and quantum sensors.
