Laboratory for Molecular Photonics
Department of Chemistry
University of Miami
Goal: The goal of this project was the identification of operating principles to switch the luminescence of semiconductor quantum dots under optical control.
Results: The Laboratory of Molecular Photonics developed a strategy to activate the luminescence of biocompatible quantum dots under the influence of optical stimulations on the basis of the photoinduced cleavage of quenchers from polymeric ligands adsorbed on their surface.
