BLUE LIGHT-EMITTING DIODES BASED ON ZINC SELENIDE QUANTUM DOTS

摘要

The present invention relates to colloid quantum dots, a method for manufacturing the colloid quantum dots, a use thereof, and an optoelectronic device comprising the colloid quantum dots. The cadmium-free colloid quantum dots include: a) a core including zinc selenide; b) at least one shell including zinc selenide which is randomly grown on the core; and c) at least one shell of a passivation material applied to the core and/or the last shell.
