a A schematic diagram of heterostructures synthesized by partially structural transform from 0D phase to 3D phase. b SEM images of 0D, 3D/0D and 3D particles, scale bars: 5 μm. c HAADF and elemental mapping, scale bars: 500 nm, d HRTEM image, scale bar: 5 nm; corresponding SAED patterns, scale bars: 5 nm−1, and e intensity profiles of 3D0.3/0D0.7(Sb) heterostructure. SAED patterns and intensity profiles are measured from the boxes shown in (d). 3D Cs2NaLuCl6 and 0D Cs3LuCl6 are identified based on the distribution of Na element in the elemental mapping (c). f XRD patterns of 3D Cs2NaLuCl6(Sb), 0D Cs3LuCl6(Sb) and 3D0.3/0D0.7(Sb) heterostructure.
