One-pot fabrication of high-quality InP/ZnS (core/shell) quantum dots and their application to cellular imaging

Chemphyschem. 2009 Jul 13;10(9-10):1466-70. doi: 10.1002/cphc.200900159.

Abstract

True colors: High-quality InP and InP/ZnS quantum dots (QDs) are obtained by means of a simple one-pot method in the presence of polyethylene glycol (PEG). Rapid and size-controlled reactions lead to highly crystalline and nearly monodisperse QDs at relatively low temperatures. The particles emit from cyan blue to far-red, and are successfully used in cellular imaging (see figure).
