Electric field effects on optical properties of semiconductor nanorods
(2009-05)We studied electric field effects on optical properties of CdSe/ZnS nanorods integrated in thin films sandwiched between transparent electrodes. It was demonstrated that P-polarized component of the photoluminescence of ... -
Förster resonance energy transfer enhanced color-conversion using colloidal semiconductor quantum dots for solid state lighting
(American Institute of Physics, 2009-10-15)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 ... -
Highly efficient nonradiative energy transfer using charged CdSe/ZnS nanocrystals for light-harvesting in solution
(American Institute of Physics, 2009-07-20)We propose and demonstrate highly efficient nonradiative Förster resonance energy transfer (FRET) facilitated by the use of positively charged CdSe/ZnS core-shell nanocrystals (NCs) for light-harvesting in solution. With ... -
Nanocrystal hybridized white light sources integrated on near UV leds
(World Scientific Publishing, 2007)We report on CdSe/ZnS core-shell nanocrystal (NC) based white light sources integrated on near-UV InGaN/GaN light emitting diodes (LEDs). We present the design, epitaxial growth, fabrication, integration and characterization ... -
Nanocrystal LEDs with enhanced external quantum efficiency enabled by the use of phosphorescent molecules
(IEEE, 2013)We report efficiency enhancement in quantum dot (QD) based LEDs with the aid of excitonic energy transfer from co-doped TCTA:Ir(ppy)3 layer to CdSe/ZnS QDs while providing spectrally pure emission. © 2013 IEEE. -
Tunable white light generating nanocyrstal-hybridized LEDs
(IEEE, 2007)We hybridize CdSe/ZnS core-shell nanocrystals on InGaN/GaN near-UV/blue LEDs to generate light widely tunable across the visible spectral range and within the white region of the chromaticity diagram with adjustable ... -
White light generating nonradiative energy transfer directly from epitaxial quantum wells to colloidal nanocrystal quantum dots
(Optical Society of America, 2009)We present white light generating nonradiative Förster resonance energy transfer at a rate of (2ns)-1 directly from epitaxial InGaN/GaN quantum wells to CdSe/ZnS heteronanocrystals in their close proximity at chromaticit ... -
White light generation with CdSe/ZnS core-shell nanocrystals and InGaN/GaN light emitting diodes
(IEEE, 2006)We present hybrid white light sources that integrate CdSe/ZnS core-shell nanocrystals on blue InGaN/GaN light emitting diodes (LED). We report on the demonstrations of white light generation using yellow nanocrystals ...
