Abstract
Quantum dot light emitting diodes (QLEDs) are rising as a promising light emitting technology. However, the widely used insulating organic ligands hamper carrier injection. Herein, we developed a bi-inorganic-ligand strategy to replace organic ligands and dispersed QDs in a benign solvent butylamine. The all-inorganic QD film shows enhanced luminescence intensity and superior thermal stability and conductivity. In the end, we exploited the first prototype all inorganic QLED.
