溶液法制备图案化量子点薄膜的研究进展

Quantum dot light emitting diode devices(QLEDs) have attracted widespread attention due to their good color rendering, high color purity, andstable performance. It can be used to manufacture display devices with ultra-thin structures or flexible structures. As the crucial light-emitting layer, high-quality quantum dot(QD) film is very important for realizing the high-performance of QLED device. This article reviews the research progress of solution-based QD films in recent years, where both the advantages and the perspectives are discussed. Furthermore, we also introduced the recently developed fiber-assisted controllable liquid transfer strategy and its application in preparing untrasmooth QD films. The review may offer guidance in preparing high quality QD film using solution processes.
