Perovskite Quantum Dots for High-performance Light-emitting Diodes Were Developed
Perovskite quantum dots are a new type of optoelectronic materials developed in recent years. With excellent optical and electronic properties such as high photoluminescence quantum yield, high brightness, high defect tolerance, and the color gamut meeting the BT. 2020 standard, Perovskite quantum dots show increasing application prospects in the field of light-emitting diodes (LED) and new displays. However, factors like large specific surface area, surface-related trap states and the surface organic insulating ligands have serious negative effects on their fluorescence quantum yield and device performance.
