Energy transfer processes in semiconductor quantum dots: bacteriorhodopsin hybrid system
(2009)The potential impact of nanoscience on energy transfer processes in biomolecules was investigated on the example of a complex between fluorescent semiconductor nanocrystals and photochromic membrane protein. The ... -
Enhanced coupling of electronic and photonic states in a microcavity-quantum dot system
(2005)Spherical microcavities consisting of a dielectric material show unique optical characteristics as resonators in combination with semiconductor nanoparticles. A high quality factor results in a very narrow bandwidth of the ... -
Experimental and Theoretical Investigation of the Distance Dependence of Localized Surface Plasmon Coupled Forster Resonance Energy Transfer
(2014)The distance dependence of localized surface plasmon (LSP) coupled Förster resonance energy transfer (FRET) is experimentally and theoretically investigated using a trilayer structure composed of separated monolayers of ... -
Influence of quantum dot concentration on F?rster resonant energy transfer in monodispersed nanocrystal quantum dot monolayers
(2010)The quantum dot (QD) concentration dependence of the optical properties of QD monolayers is shown to be dominated by Forster resonant energy transfer (FRET) from smaller to larger QDs in the ensemble. With increasing QD ... -
Interaction of surface plasmons with CdTe quantum dot excitons
(SPIE, 2005)A 5-fold enhancement in the luminescence of CdTe nanocrystal quantum dots (QDs) is observed when they are placed in proximity to a nanostructured Au film deposited by pulsed laser deposition technique. No enhancement is ... -
Size selective photoluminescence excitation spectroscopy in CdTe quantum dots
(2003)We present a photoluminescence and photoluminescence excitation study of CdTe quantum dots, prepared via a novel organometallic approach. The global photoluminescence (excited at the energy above the absorption edge) ...
