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.
