Crystal structure of perovskite nanoplatelets (NPLs). a Transmission electron microscopy (TEM) image of CsPbBr3 NPLs. The scale bar is 50 nm. b High-resolution transmission electron microscopy (HRTEM) images of CsPbBr3 NPLs and the Fourier transform diffraction spot. The scale bar is 5 nm. c X-ray diffraction (XRD) pattern of CsPbBr3 NPLs. d Atomic force microscope (AFM) image (500 nm × 500 nm) of CsPbBr3 NPLs on SiO2/Si substrate. The scale bar is 100 nm. e The single CsPbBr3 NPL shown in a with a height ~4 nm and a lateral size ~30 nm corresponding to TEM size shown in b. The scale bar is 10 nm. f Thickness statistics of CsPbBr3 NPLs which shows an average thickness ~3.8 nm
