  "abstract": "Structural and optical characterization of Eu3+ doped atomically precise bismuth oxido nanoclusters (BiO‐NCs) of about 2 nm in size is reported. The BiO‐NC [Bi38O45(NO3)24(dmso)28]:Eu (C‐1D:Eu) is transformed into soluble methacrylate (−OMc) coordinated [Bi38O45(OMc)24(dmso)4]:Eu·4dmso·4H2O (C‐2D:Eu) and [Bi38O45(OMc)24(EtOH)10]:Eu·4EtOH (C‐2E:Eu) by ligand exchange and without changing the amount of Eu3+ doping (ω ≈ 1%). Based on SC XRD analysis of C‐1D:Eu and C‐2E:Eu partial substitution of the bismuth atoms with preference in the inner {Bi6O9} core of the {Bi38O45} cluster is suggested. Temperature dependent photoluminescence studies show bismuth‐ and europium‐based dual emission at low temperatures, whereas only the latter is preserved at room temperature. As a result of the low‐symmetry environment of Eu3+ a remarkable intensity of the 5D0→7F0 (electric dipole) transition is observed, accompanied by lifetimes of about 2 ms and quantum yields ranging from 53% (C‐2D:Eu) to 65 % (C‐1D:Eu). The solubility of C‐2E:Eu enables its use for the synthesis of organic–inorganic hybrid materials. Thus, transparent hybrid materials were prepared by radical copolymerization of methyl methacrylate, 2‐hydroxyethyl methacrylate and C‐2E:Eu, showing distinct photoluminescence characteristics even with a low Eu3+ content of 2.7·10−5 mol%.",
