a XRD of CsPbBr3:PEACl (1:1) film. b PL spectra of CsPbBr3:PEACl (1:1) film at 273 K and 173 K. c Absorbance of CsPbBr3:PEACl (1:1) film. d Transient absorption (TA) spectra of CsPbBr3:PEACl (1:1) film at different timescales. e TA signal measured at a probe wavelength of 480 nm reveals distinct bleaching of the 3D phase in the CsPbBr3:PEACL (1:1) film.
