A Simple Room-Temperature Preparation of Colloidal ZnO Quantum Dots from Homogeneous Polar Aprotic Solutions

摘要

A simple, versatile, and scalable procedure for synthesizing high-quality colloidal ZnO quantum dots from homogeneous polar aprotic solutions has been developed. TEM and x-ray diffraction data show that the nanocrystals synthesized by this procedure are highly crystalline, pseudo-spherical, and have a narrow size distribution. This procedure allows large quantities of homogeneous ZnO quantum dots to be prepared with relative ease, and is also conducive to the introduction of dopants.
