WebOct 13, 2024 · In the XRD results, it is also observed that the diffraction peak of the IJP-CsPbBr 3 sample shifts to a larger 2θ value (Figure S10b, Supporting Information). Zhao et al. [ 26 ] calculated that the lattice volume would expand by 2.18 times during the phase transition from the orthorhombic PbBr 2 phase to the cubic CsPbBr 3 phase. WebJun 24, 2024 · The reduced size was also reflected from the broadening of XRD peaks, where the average crystalline dimension can be calculated according to the Scherrer equation. As shown in Fig. 2 d, the full width at half maximum increased from 2.32° to 2.54°, indicating a thickness decreasing from 3.4 to 3.1 nm.
