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.
量子点发光二极管（QLED）作为一种很有前景的发光技术正在兴起。然而，广泛使用的绝缘有机配体会阻碍载流子注入。在此，我们开发了一种双无机配体策略来取代有机配体，并将量子点分散在良性溶剂丁胺中。全无机量子点薄膜显示出增强的发光强度、优异的热稳定性和导电性。最后，我们开发了首个全无机量子点发光二极管原型。
