A one-step aqueous synthetic route to extremely small CdSe nanoparticles.
By employing Na2Se as a selenium source, we demonstrate that extremely small ( approximately 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.
