    Controllable broadband multicolour single-mode polarized laser in a dye-assembled homoepitaxial MOF microcrystal by He, Huajun, Cui, Yuanjing, Li, Hongjun, Shao, Kai, Chen, Banglin, Qian, Guodong

    Published 2021
    “…Here, we demonstrate a single crystal with multiple segments based on the host-guest metal-organic framework ZJU-68 hierarchically hybridized with different dye molecules generating controllable single-mode green, red, and near-infrared lasing, with the lasing mode mechanism revealed by computational simulation. The segmented and oriented assembly of different dye molecules within the ZJU-68 microcrystal causes it to act as a shortened resonator, enabling us to achieve dynamically controllable multicolour single-mode lasing with a low three-colour-lasing threshold of ~1.72 mJ/cm2 (approximately seven times lower than that of state-of-the-art designed heterostructure alloys, as reported by Fan F et al. …”
