ZnO nanocrystals of high quality with pure UV‐emitting properties were synthesized through a new microfluidic approach based on supercritical fluids and separation of nucleation/growth and functionalization steps (see picture). The as‐synthesized ZnO nanocrystals (NCs) show exciton luminescence without classical defect‐state luminescence.
ZnO‐Nanokristalle hoher Qualität und mit rein UV‐emittierenden Eigenschaften wurden in einem neuen Mikrofluidikverfahren hergestellt, das überkritische Fluide verwendet und Keimbildungs‐/Wachstums‐ und Funktionalisierungsschritt trennt (siehe Bild). Diese ZnO‐Nanokristalle (NCs) zeigen Excitonen‐Lumineszenz ohne die klassische Fehlstellen‐Lumineszenz.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
