Quantum Dot Light-Emitting Diodes with External Quantum Efficiency Exceeding 30% Enabled by a Crown Ether-Modified Electron Transport Layer
{{output}}
Zinc magnesium oxide nanoparticles (ZnMgO NPs), known for their excellent optoelectronic properties, are widely used as the electron transport layer (ETL) in high-performance quantum dot light-emitting diodes (QLEDs). However, their high conductivity and abund... ...
