摘      要：Multi-band microlasers based on single microcrystalline materials with Fabry-Perot(F-P) cavities are critically and technologically essential. Here, we demonstrate simultaneous dual-band lasing output(615 and 685 nm) in metal-organic frameworks(MOFs) and organic dyes hybrid single crystals, which support F-P resonances. Through a two-step assembly strategy, two different types of cationic pyridinium hemicyanine dye molecules can be encapsulated into the channel pores of anionic bioMOF-1-2 Me successfully. In addition, the employment of the host-guest system significantly increases the dye loading, enhances luminescent efficiency, and diminishes the aggregation-caused quenching(ACQ) effect in the resultant MOFs/dye *** finding not only combines the characteristic of MOFs materials with excellent luminescent properties of organic dyes, but also points out a simple and promising strategy to design multi-band microlasers based on F-P mechanism, opening a low-cost avenue for the rational design of miniaturized lasers in the future.
