Abstract： The nitrogen-doped carbon dots （N-CDs） were prepared by solvent-thermal method in this study，and the Al-based metal-organic frameworks decorated with N-CDs composite material （MIL53（A1） NH2@N-CDs） was fabricated by in-situ hydrothermal method. The abundant carboxyl functional groups on the surface of N-CDs enabled their participation in the coordination assembly process of AlMOFs，and through the spatial hindrance effect， the orientation and growth process of MOFs crystals were restricted， thereby achieving the morphology control of MOFs， transforming them from threedimensional gear-like structures to short rod-like cross-linked nano-flowers.Additionally，based on the fluorescence properties of MIL-53（Al）. ⋅NH2@N-CDs ， fluorescent-tunable multi-color light-emitting diode（LED） devices were further fabricated. The results demonstrate that N-CDs can effectively regulate the morphology and fluorescence properties of MIL-53（Al）- NH2 . Furthermore， the mechanism underlying the regulation of MIL-53（Al）- NH2 assembly behavior by N-CDs was analyzed， which provided a design method for synthesizing novel MOFs morphological structures， and also offered a new insight for developing high-performance multi-color LED devices.
