摘要：

A mixture of PbBr2 and YbBr3.nH(2)O in a dimethyl sulfoxide (DMSO) solution yielded single crystals of a lead halide perovskite precursor with ytterbium, bis[octakis(dimethyl sulfoxide)ytterbium(III)]pentabromidoplumbate(II) tribromide with dimethyl sulfoxide as co-crystallite, [Yb(C2H6OS)(8)][PbBr5](0.5)Br-1.5.0.5C(2)H(6)OS. The complex ions PbBr53- and Yb(DMSO) (3+)(8) are present in the crystal together with three Br- ions and DMSO molecules. X-ray crystallography revealed that the Br- ions in YbBr3 are replaced by the solvent and bound to a Pb-II atom or remain free. The presence of PbBr53- units, which are molecular ions with a square-pyramidal structure, is also observed. These single crystals react with a caesium chloride solution, exhibiting near-infrared (NIR) luminescence by visible photoexcitation, suggesting the formation of Yb3+-doped lead halide perovskites (CsPbBr(3-x)Clx.Yb3+).
