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. The as-synthesized ZnO nanocrystals (NCs) show exciton luminescence without classical defect-state luminescence.
