Fig. 2

a SEM image of the hot-injection prepared Cu4I6(pr-ted)2 microcubes. The inset shows a high-magnification SEM image of an individual microcube. b TEM and elemental mapping images of single microcubes. c Excitation-photoluminescence mapping of the Cu4I6(pr-ted)2 microcubes. The inset shows a photograph of the UV-induced luminescence of the microcubes (365 nm). d PLQYs of the microcubes as a function of annealing time (200 °C, N2 atmosphere). e Comparison of the photoluminescence intensity of the Cu4I6(pr-ted)2 microcubes measured at various temperatures. f Decay curve of the green emission (535 nm) of the microcubes. g Photoluminescence intensity of an aqueous dispersion of Cu4I6(pr-ted)2 microcubes as a function of incubation time
