A one-step aqueous synthetic route to extremely small CdSe nanoparticles

By employing Na2Se as a selenium source, we demonstrate that extremely small (∼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.

Extremely small (∼1 nm) mercapto acid-stabilized CdSe nanoparticles with near band-gap photoluminescence in the blue spectral range were synthesized through a one-step aqueous route.Figure optionsDownload as PowerPoint slide
