Annotation
In this study, FAPbI3 perovskite quantum dots were synthesized at room temperature using ligand-assisted redeposition in the presence of various antisolvents. The resulting red-emitting quantum dots had an absorption edge at a wavelength of 700 nm, and the emission maxima appeared in the range of 650 nm to 800 nm, depending on the type of antisolvent. In addition, these results showed that the appropriate selection of the volume ratio of ligands during synthesis plays an important role in the formation of the quantum dot size. The synthesized FAPbI3 perovskite quantum dots can be used to prepare solar cells, LED lamps, and photovoltaic (PV) devices due to their excellent optoelectronic properties.
