In recent years, lead-free perovskite materials, represented by Cs 2 NaInCl 6, have achieved a rapid breakthrough of luminous quantum yield from zero to near-unity by Ag/Na and In/Bi alloying schemes.
Quantum-dot light-emitting diodes (QLEDs) have shown great potential in display and lighting applications. In particular, the incorporation of zinc oxide nanoparticles (ZnO NPs) as the electron ...
