Abstract

The threshold of the absorption spectra of colloidal cadmium sulfide (CdS) quantum dots in electrolytic solutions is shown to shift as the concentration of the electrolyte is varied. The shift in the absorption threshold as a function of the electrolytic concentration is given by electrolytic screening of the field caused by the intrinsic spontaneous polarization of these wurtzite quantum dots. These electrolyte-dependent absorption properties will be compared with Fermi-level tuning in carbon nanotubes in electrolytic environments. Moreover, concepts for integrating such colloidal quantum dots in high density networks with biomolecular links will be discussed. MAS is grateful for the support and guidance of Dr. Dwight Woolard of the ARO, and MD gratefully acknowledges the support of NSF and SRC.
