Lead chlorine cluster assembled one-dimensional halide with highly efficient broadband white-light emission

One new type of hybrid lead halide of [DTHPE] 2 Pb 3 Cl 10 has been synthesized and characterized containing a one-dimensional (1D) wavelike [Pb 3 Cl 10 ] 4− chain based on a corner-shared [Pb 3 Cl 11 ] cluster. Remarkably, this cluster-based 1D chain displays intrinsic broadband white light emission with a high quantum efficiency of 19.45% exceeding those of previously reported typical two-dimensional perovskites. One new lead chlorine cluster assembled 1D non-perovskite halide of [DTHPE] 2 Pb 3 Cl 10 was synthesized which displays strong broadband bluish white light emission with a high photoluminescence quantum efficiency of 19.45% exceeding those of previously reported 2D lead perovskites.
