Abstract
Synergistic Hybrid-Ligand Passivation of Perovskite Quantum Dots This illustration demonstrates multi-functional CsPbI3 perovskite quantum dot (PQD) solids with high luminescence, conductivity, and stability fabricated by synergistic hybrid-ligand exchange and passivation strategies. The multiple interactions between introduced ligands not only improve inherent properties but also suppress the dimensionality change that cause severe stability degradation of PQDs. Therefore, hybrid-ligand strategies enable realizing highly efficient and stable optoelectronic device.
