a Schematic diagram illustrating the transfer-printing method used to prepare chiral-2D/3D perovskite heterostructures. b Cross-sectional SEM image of the 2D/3D perovskite films. GIWAXS patterns of 3D (c) and 2D/3D (d) perovskite films. e Absorption, f photoluminescence (PL) emission, and g time-resolved PL spectra of 3D and 2D/3D perovskite films.
