Abstract
A method for forming CsPbBr3 perovskite nanocrystals into a two-dimensional (2D) nanosheet includes providing CsPbBr3 perovskite nanocrystals; mixing the CsPbBr3 perovskite nanocrystals into a mixture of a first solvent and a second solvent, to form a solution of the CsPbBr3 perovskite nanocrystals, the first solvent, and the second solvent; and forming an optoelectronic device by patterning the CsPbBr3 perovskite nanocrystals into a nanosheet, between first and second electrodes. The first solvent is selected to evaporate before the second solvent.
