The Chemistry of Perovskite Quantum Dots for Display Technologies
Quick fact
Perovskite quantum dots can emit light with a color purity (full width at half maximum) as narrow as 12–20 nm, nearly twice as pure as traditional cadmium-based quantum dots, enabling displays to show a wider and more accurate range of colors.
Why this is interesting
Your phone's screen might soon rely on crystals that are only a few nanometers wide—but they can already glow with colors more vivid than nature. What makes these tiny crystals so special?
