Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

Small, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...

Decoupling Transparency and Electron Injection in Ultrathin Ag Electrodes Using an Al/MoO3 Double Seed Layer for Transparent Quantum Dot Light‐Emitting Diodes

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Transparent quantum dot light‐emitting diodes (Tr‐QLEDs) employing an Al/MoO3 double seed layer decouple optical transparency from electron injection in ultrathin Ag electrodes. The functionally separated seed layers enable low optical loss and efficient charge injection simultaneously, resulting in improved electroluminescent performance, enhanced ...
