Extended Data Fig. 1

a–c, (R-MBA)2PbI4 deposited on (AlxGa1−x)0.5In0.5P surface. d, TFB/(R-MBA)2PbI4/(AlxGa1−x)0.5In0.5P. e, IZO/Al2O3/TFB/(R-MBA)2PbI4/(AlxGa1−x)0.5In0.5P. The (R-MBA)2PbI4 exhibits impinged spherulites with no gaps observed. The spherulitic structure is maintained through the deposition of TFB and IZO. f, Cross-sectional imaging of the LED with visible layer from top down: gold/IZO/(R-MBA)2PbI4/p-cladding/MQW/n-cladding.
