J Am Chem Soc. 2011 Oct 19;133(41):16422-4. doi: 10.1021/ja2079509. Epub 2011 Sep 27.

Abstract

HgTe colloidal quantum dots are prepared via a simple two-step injection method. Absorption and photodetection with sharp edges, as well as narrow photoluminescence, are tunable across the near and mid-IR between 1.3 and 5 μm.
