Ultra-small PbSe Quantum Dots Synthesis by Chemical Nucleation Controlling

Ultra-small PbSe quantum dots (QDs) were synthesized using conventional hot-injection method. A small amount of Sn was used as a nucleation promotion agent to control nucleation and growth during the QDs synthesis process. The average diameter of the QDs is about 1.6 nm, of which absorption peak cen...
