| 中文摘要: |
| 含有氮空位(nitrogen vacancy,NV)色心的荧光纳米金刚石(fluorescent nanodiamonds,FNDs),由于其独特的性质,在量子传感、量子计算和荧光成像等领域具有广泛的应用前景。使用有序多孔的金属有机框架(metal-organic frameworks,MOFs)将FNDs功能化,可以为FNDs的固定以及其他物质与FNDs表面的相互作用提供明确的位点,为量子应用创造一个可调控的环境。研究了一种FNDs与MOFs的复合材料。将FNDs封装在生物相容性的MOFs 咪唑酸沸石骨架–8(zeolite imidazolate framework-8,ZIF-8)中,成功保留了FNDs的荧光和量子传感性能,并观察到了FNDs被ZIF-8 选择性封装后,其荧光有效寿命发生了变化。此外,还研究了不同合成条件对FNDs@ZIF-8尺寸和形态的调控效果。通过深入探讨FNDs@MOFs复合材料的性能,揭示了FNDs在复合材料中的量子特性,为设计更灵活且高性能的荧光成像装置和量子传感器提供了新途径。 |

| 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 conditions on 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. |
