(a) Transmission electron microscopy (TEM) image of FAPbBr3 NCs. The black dots correspond to FAPbBr3 NCs having an average size of 10–15 nm. (b) Particle size distributions measured via small angle x-ray scattering technique (SAXS) the as synthesized FAPbBr3 NCs with an average size of 12–14 nm. (c) The high-resolution transmission electron microscopy (HR-TEM) of the FAPbBr3 NCs with its fast Fourier transformation (FFT) image shown in the inset. (d) X-ray diffraction (XRD) patterns for drop cast FAPbBr3 NCs.
