Schematic illustration showing the fabrication of a spatially patterned perovskite film. a) Drop casting PbCO3 particles dispersed in methanol onto a glass substrate results in a PbCO3 thin film that acts as the reactive canvas. b) Stamping MAX in IPA on the canvas results in, c) spatially-controlled conversion of the PbCO3 into a MAPbX3 perovskite. d) Upon UV irradiation, the converted areas emit light with a color that is controlled by adjusting the halide moiety of the perovskite.

As a proof of principle, Lukas Helmbrecht and Wim Noorduin 'painted' a portrait of Marie Curie in a perovskite semiconductor layer. Both researchers work at the AMOLF research institute at Amsterdam Science Park.
