We report two-dimensional (2D) metal–organic framework nanosheets (MONs) integrated with optical fiber (OF) that enable tunable light emission and biocompatible microendoscopy. Luminescent 2D frameworks based on Eu3+, Tb3+, and Y3+ ions are employed to produce freestanding MONs via freeze–thaw exfoliation, followed by integration onto the OF through solution dripping. The resulting MONs exhibit large aspect ratios of up to 2300:1 and display red, green, and blue photoluminescence (PL), respectively. Their integration with OFs enables PL color mixing, yielding tunable emission ranging from yellow to quasi-white. The MON-integrated OFs are subsequently used for light emission and in vivo microendoscopy of Casper fish, paving the way for efficient and sustainable 2D materials in optical and biomedical technologies.
