Fluence dependence of lattice deformation. TR-XRD patterns of CsPbBr3 NCs 40 ps after photoexcitation at a range of excitation fluences. The orthorhombic peaks are delineated with gray solid lines and the high-symmetry black dashed. A solid black line also denotes ΔS = 0 and arrows emphasize how the TR-XRD pattern evolves with power. Inset: Irreversible percent loss of peak intensity versus excitation power. The error bar indicates standard deviation in the measurement
