Role of Conjugated Structure of Cross-linkers in Patterned QLEDs
Nano LettersDirect optical lithography is a promising method for the high-resolution patterning of colloidal quantum dots (CQDs) in optoelectronic devices. However, this approach requires photo-cross-linkers that ensure strong chemical binding without degrading CQD ligands, while also supporting efficient charge transport.

Thickness Estimation Method for Every Functional Layer of QLEDs
ACTA PHOTONICA SINICA, 2017To balance the carrier injection in Quantum Dot Light Emitting Diode (QLEDs), a method to determine the thickness of each functional layer was proposed. The thickness of EL was set firstly, the thickness of Electron Transport Layer (ETL) was determined through tunneling model. On this basis, the thickness of Hole Injection Layer (HTL) was determined at

Organic–Inorganic Hybrid Passivation Enables Perovskite QLEDs with an EQE of 16.48%
Advanced Materials, 2018AbstractPerovskite quantum dots (QDs) with high photoluminescence quantum yields (PLQYs) and narrow emission peak hold promise for next‐generation flexible and high‐definition displays. However, perovskite QD films often suffer from low PLQYs due to the dynamic characteristics between the QD's surface and organic ligands and inefficient electrical ...
