Tuning the Photoluminescence of Germanium Nanocrystals through Surface Bound Functional Groups

A room temperature, solution phase method for production of size monodisperse germanium nanocrystals (Ge NCs) terminated with different chemical functionalities (epoxy, acetate, amine, carboxylic acid, and alkyl) is reported. Ge NC photoluminescence spectra show that the emission can be tuned from the UV to the blue/green through choice of ligand.
