研究目的
Investigating the electroluminescence mechanisms in Cd-free CuInS2/ZnS quantum-dot based light-emitting diodes (QLEDs) and exploring the influence of hole transporting layers (HTLs) on device performance and electroluminescence mechanism.
研究成果
The working mechanism of QLEDs based on CuInS2/ZnS QDs is intensely dependent on the HTL, with both the energy level alignment and the electron mobility of HTL playing critical roles. Highly efficient deep red CuInS2/ZnS QLEDs can be achieved by selecting suitable HTLs, demonstrating the potential for Cd-free QLEDs in lighting and display applications.
研究不足
The study focuses on the influence of HTLs on QLED performance and electroluminescence mechanisms but does not extensively explore the optimization of other device components or the scalability of the fabrication process.
