Highly luminescent MAPbI₃ perovskite quantum dots with a simple purification process via ultrasound-assisted bead milling.

ABSTRACT: Organic-inorganic hybrid lead halide perovskite quantum dots (QDs) have various excellent optical properties, and they have drastically enhanced the field of light-emitting diode (LED) research. However, red-emissive CH₃NH₃ (MA) PbI₃ QDs have worse optical properties compared with those of green-emissive MAPbBr₃ QDs due to their instability under high-moisture and high-temperature conditions. Therefore, it is quite difficult to prepare MAPbI₃ QDs with good optical properties via bottom-up methods using conditions involving high temperature and high-solubility solvents. On the other hand, top-down methods for preparing MAPbI₃ QDs under an air atmosphere have attracted attention; however, there are issues, such as PL em
