A research team has developed a hierarchical-shell perovskite nanocrystal technology that simultaneously overcomes the long-standing instability of metal-halide perovskite emitters while achieving record-breaking quantum yield, operational stability, and scalability. This work paves the way for next-generation vivid-color display technologies.

The research is published in the journal Science as a cover article.

The team was led by Professor Tae-Woo Lee (Department of Materials Science and Engineering, Seoul National University, Republic of Korea & SN Display Co., Ltd).
