Quantum Dot Mystery Resolved
The mechanism of quantum dot formation may not be what people thought, a study reveals (J. Am. Chem. Soc., DOI: 10.1021/ja103805s). A common source of selenium for the synthesis of CdSe or PbSe quantum dots is trioctylphosphine selenide (TOPSe). But when Todd D. Krauss, Christopher M. Evans, and Meagan E. Evans of the University of Rochester combined high-purity TOPSe with Pb(oleate)2, they . . .
