Förster resonance energy transfer enhanced color-conversion using colloidal semiconductor quantum dots for solid state lighting

In this paper, we present Förster resonance energy transfer FRET -enhanced color-conversion using colloidal semiconductor quantum dot nanocrystals NCs to make reddish-orange light-emitting diodes for use in ultraefficient solid state lighting. To achieve FRET enhancement at 614 nm, we use an energy gradient hybrid structure made of cyanand orange-emitting CdSe/ZnS NCs PL=492 and 588 nm in solut...

Efficient radiative and nonradiative energy transfer from proximal CdSe/ZnS nanocrystals into silicon nanomembranes.

We demonstrate efficient excitonic sensitization of crystalline Si nanomembranes via combined effects of radiative (RET) and nonradiative (NRET) energy transfer from a proximal monolayer of colloidal semiconductor nanocrystals. Ultrathin, 25-300 nm Si films are prepared on top of insulating SiO(2) substrates and grafted with a monolayer of CdSe/ZnS nanocrystals via carboxy-alkyl chain linkers. ...

Complete Quenching of CdSe Nanocrystal Photoluminescence by Single Dye Molecules

Much of the current research into semiconductor nanocrystal (NC) photochemistry has focused on their potential application as biological reporters, as light harvesting elements in solar energy conversion systems, or as tunable emitters in light-emitting diodes (LEDs). These applications all necessitate energy or charge-carrier transfer between semiconductor materials and molecular species. For ...

Combined Bimolecular Fluorescence Complementation (BiFC) and Förster Resonance Energy Transfer (FRET) Reveals Ternary SNARE Complex Formation in Living Plant Cells

Scanning near-field optical microscopy using semiconductor nanocrystals as a local fluorescence and fluorescence resonance energy transfer source.

Local fluorescence probes based on CdSe semiconductor nanocrystals were prepared and tested by recording scanning near-field optical microscopy (SNOM) images of calibration samples and fluorescence resonance energy transfer SNOM (FRET SNOM) images of acceptor dye molecules inhomogeneously deposited onto a glass substrate. Thousands of nanocrystals contribute to the signal when this probe is use...
