Extended Data Fig. 2: HR-TEM images of nanocrystals.
From: Ligand-engineered bandgap stability in mixed-halide perovskite LEDs
a, b, HR-TEM images of neat nanocrystals at different magnifications. c, Fast Fourier transformation of the selected region in b, in which the interplanar lattice spacing of the cubic phase is 0.60 and 0.42 nm for the {001} and {110} family of planes. d, e, HR-TEM images of E+G-treated nanocrystals at different magnifications. f, Fast Fourier transformation of the selected region in e showing a similar cubic structure to neat nanocrystals.
