Abstract

Uniform Zn_xCd_1-xSe nanocrystals have been prepared at the artificially designed water-oil interface using Na₂-SeO ₃, Cd(NO₃)₂, and Zn(NO₃)₂ as precursors. The chemical composition and band gap of the Zn _xCd_1-xSe nanocrystals can be adjusted via different combinations of source material. The coating of a SiO₂ shell could transform the hydrophobic particles into hydrophilic particles. An advantage of this method is that a water phase could be added to the oleic acid (OLEA) synthesis system, which could be extended to make the synthesis of various nanocrystals more simple and flexible.
