Nanocrystals light up LED chips
Simplified and more efficient white light-emitting diodes (LEDs) could result from replacing external colour-converting phosphors with CdSe-based nanocrystals that are incorporated directly into the p-n junction.
Scientists from the Los Alamos and Sandia laboratories in New Mexico, US, have fabricated the first LEDs that use an all-inorganic, nanocrystal-based architecture.
