Spatially selective optical tuning of quantum dot thin film luminescence.
Photolithographically generated patterns have been created on immobilized CdSe QD thin films by fine-tuning their optical properties (intensity and emission wavelength) postsynthetically. These optically modified QDs show enhanced selectivity for binding of different ligands, affording the ability to fabricate optically reconfigurable surfaces for display or sensing applications. The patterns may be readily generated with any typical optical lithographic approach.
