Fig. 2 Relevant SR-XRD patterns of β-CsPbI3[11] (a) XRD patterns acquired from a CsPbI3 thin film and powders scratched from its films. Brown lines indicate the standard β-CsPbI3 XRD pattern calculated for Cu Kα1 radiation for the tetragonal perovskite structure at 518 K; (b) GIWAXS data from β-CsPbI3 films; (c) Azimuthally integrated intensity profiles for the β-CsPbI3 perovskite films annealed at different temperatures (30, 80, 100, 150, 190, 210, 230, 250 ℃)
