Abstract: Precisely patterning large-area quantum dot (QD) nanoparticles is an essential technique for enhancing high-resolution and high-performance in the next generation display --- QLEDs. However, conventional solution-based assembly techniques suffer from trade-offs between large-scale and spatial… read more here.
