a ADF-STEM image of (CsPbI3)0.1(agZIF-62)0.9 composites sintered at 350 °C. b EELS core loss spectra acquired from the marked points shown in TEM image with background subtracted. c, d Atomic pair distribution functions for (CsPbI3)0.50(agZIF-62)0.50 composites sintered at 350 °C. Pair distribution function D(r) calculated via Fourier transform of the X-ray total scattering function. Panel (d) is the enlarged fitted data in the r range of 1.5−12 Å.
