Abstract:
Colloidal quantum dots (QDs) possess superb optoelectronic properties suitable as light emitters. However, the toxicity of classical Cd/Pb QDs with high luminescence efficiency restricts their further industrial light-emitting applications. Heavy-metal-free ZnSe(Te) QDs are regarded as the most promising alternative of Cd/Pb-based QDs blue emitters, which are expected to solve the defect that InP QDs struggle to achieve efficient blue emission. However, the realization of ZnSe(Te) QDs and light-emitting devices with high efficiency, high stability, and narrow emission is confronted with huge challenges. In this review, the synthesis of ZnSe(Te) QDs is reviewed, and their improvement strategies including bandgap engineering and surface passivation are introduced and discussed. The progress regarding blue ZnSe(Te)-based light-emitting applications is summarized. Finally, a brief outlook is provided, pointing out the current facing challenges, their possible solutions, as well as future development directions.
