I review light production from quantum dot nanocrystals embedded in a semiconducting polymer. Integrable optoelectronics is facilitated in this processible material system - one which may conveniently be combined with silicon electronics, passive optics, and RF platforms. Synthetic conditions determine nanocrystal diameter and thereby tune, through the quantum size effect, the spectrum of optical emissions from the quantum dots. We show that it is possible to span across and beyond the 1.3-1.6 um spectrum of optical communications. Nonradiative recombination from the nanocrystals' surface is addressed by choosing stabilizing, passivating organic ligands which nevertheless permit energy transfer from polymer to nanocrystals.
