A research team led by Professor Tae-Woo Lee at Seoul National University has developed a revolutionary technology to mass produce ultra-high color purity perovskite nanocrystals (PeNCs), the core material for next-generation displays, without the need for high temperature, vacuum, or specialized gas facilities. This study, published in Nature, proves that 100% photoluminescence quantum yield (PLQY) can be maintained from lab to industrial scale, a major breakthrough for commercializing perovskite technology.

Why it matters

Perovskites are the leading candidates for ultra-high definition TVs and next-generation immersive applications like Augmented Reality (AR) and Virtual Reality (VR) displays due to their high color purity, excellent optoelectronic properties, and low material costs. This new mass production method overcomes key limitations of existing perovskite synthesis techniques, paving the way for widespread commercial adoption.

The details

Professor Lee's team developed a 'Cold-injection' method that allows for high quality PeNC synthesis under ambient conditions, eliminating heat-related safety issues and significantly reducing production costs. The team discovered a previously unknown 'pseudo-emulsion' mechanism that slows down the crystal formation rate, suppressing defects and enabling highly crystalline, uniform PeNCs. This approach enables consistent high productivity, even at large 20-liter reactor scales.

  • The study was published in the journal Nature on February 18, 2026.
  • Professor Lee's team has been a global leader in perovskite light-emitting diodes (PeLEDs) for the past decade, securing pioneering patents in 2014 and achieving major breakthroughs in efficiency in 2015 and 2022.
