Electron/Hole Injection and Transport Materials in Quantum Dot Light‐Emitting Diodes

Summary

Quantum dot light‐emitting diodes (QDLEDs) are an exciting technology with the potential for high‐performance displays and lighting. The efficiency and stability of QDLEDs are critical factors in their widespread adoption, and both the hole transport layer and electron transport layer play significant roles in these properties. In QDLEDs, the charge transport mechanism involves the movement of electrons and holes through the QD layer, which leads to the recombination of electron–hole pairs and the emission of light. Electron injection materials play a crucial role in determining the performance of QDLEDs, including their efficiency, brightness, and lifetime. Hole transport materials are a key component of QDLEDs, which are a type of LED that uses QDs to emit light. Typically, QDLED devices have a hybrid structure that includes an organic hole injection/transport layer and an inorganic electron injection/transport layer.
