A method of preparing luminescent nano-sheets includes preparing a precursor emulsion solution containing a metal halide and RNH 3 X, with the molar ratio of metal halide to RNH 3 X in a range of approximately 0.6 to approximately 0.8; demulsifying the precursor emulsion solution to obtain perovskite quantum dots and a demulsified solution; and forming the luminescent nano-sheets by allowing the perovskite quantum dots to self-assemble into nano-sheets. X represents halogen, and R represents a group selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl, heteroaryl, and heterocyclyl. |
