By breaking the restriction of mirrors, random lasers from a disordered medium have found unique applications spanning from displays, spectroscopy, biomedical treatments, to Li-Fi.Gain media in the form of two-dimension with distinct physical and chemical properties may lead to the next-generation of random lasers. Graphdiyne, a 2D graphene allotrope with intrigued carbon hybridization, atomic lattice, and optoelectronic properties, has attracted increasing attention recently. Herein, the photon emission characteristics and photo-carrier dynamics in graphdiyne are systematically studied, and the multicolor random lasers have been unprecedently realized using graphdiyne nanosheets as the gain. Considering the well bio-compatibility of graphdiyne, these results may look ahead a plethora of potential applications in the nanotechnology platform based on graphdiyne.
