High color purity blue quantum dot light‐emitting diodes (QLEDs) have great potential applications in the field of ultra‐high‐definition display. However, the realization of eco‐friendly pure‐blue QLEDs with a narrow emission linewidth for high color purity remains a significant challenge. Herein, a strategy for fabricating high color purity and efficient pure‐blue QLEDs based on ZnSeTe/ZnSe/ZnS quantum...
ZnSeTe Quantum Dots
In article number 2303247, Jialong Zhao, Sheng Cao, Yunjun Wang, and co‐workers propose a strategy for fabricating high‐color purity and high‐efficiency pure blue quantum dot (QD) light‐emitting diodes (QLEDs) using eco‐friendly ZnSeTe/ZnSe/ZnS QDs. Precisely controlling the internal ZnSe shell thickness could weaken the exciton‐ longitudinal optical (LO) phonon coupling strength...
