A one-step aqueous synthetic route to extremely small CdSe nanoparticles
By employing Na2Se as a selenium source, we demonstrate that extremely small (similar to 1 nm) mercapto acid-stabilized CdSe nanoparticles can be conveniently prepared in water. The as-prepared nanoparticles start to show dominant near band-gap photoluminescence in the blue spectral range and show high photoluminescence in the green spectral range. (c) 2007 Elsevier Inc.
