Perovskite quantum dots, refer to three dimensions of space within 100 nanometers. It has the characteristics of easily tuned luminescence, narrow emission spectrum peak, high fluorescence quantum yield and simple synthesis conditions. To synthesize the perovskite quantum dots, many approaches have been presented including ligand-assisted reprecipitation (LARP), hot-injection, ultrasonication and others. The methods are still under development to synthesize stable, effective and high-quality perovskite QDs.
