Read moreThe promise of photoluminescent semiconductor nanocrystals
Semiconductor nanocrystals emit light at wavelengths that can be tuned by particle size and composition, and are more stable to light than organic dyes, so hopes for their applied use are high. When coated with such agents as surfactants and a semiconductor with a wide band gap, these nanocrystals show strong photoluminescence.
