Literature review reveals defect passivation improves fluorescence yield in perovskite quantum dots, indicating potential for Micro-LED displays.

Defect passivation technology significantly enhances the fluorescence quantum yield and stability of perovskite quantum dots.
Photoluminescence quantum yield can reach over 90%, while environmental stability increases humidity tolerance by 3-5 times.
Literature review employed strategies like ligand modification and ion doping to suppress defects in perovskite quantum dots.
Further optimization is required for long-term stability and large-scale manufacturing for Micro-LED applications.

Yutong Guo (2025) studied this question.
