Superior warm-White light-emitting diodes integrated with quantum dot nanophosphors for high luminous efficacy and color rendering
(Optical Society of America, 2011)
Quantum dot nanophoshor hybridized warm-white LEDs are reported to exhibit high photometric performance of luminous efficacy exceeding 350 lm/Wopt and color rendering index close to 90 at correlated color temperatures <3000 ...
Wavelength dependent color conversion of CdSe/ZnS core/shell nanocrystals for white LEDs
Nanocrystals (NCs) provide narrow emission spectrum that can be conveniently tuned using quantum size effect. This ability to adjust and control emission spectrum of NCs makes them strong candidates for use in white color ...
Near-UV InGaN/GaN-based dual-operation quantum optoelectronic devices
We present a novel dual-operation InGaN/GaN based quantum optoelectronic device (QOD) that operates as a quantum electroabsorption modulator in reverse bias and as a light emitter in forward bias in the spectral range of ...
Plasmonic nanoparticle enhanced and extended performance of light-sensitive nanocrystal skins
(Materials Research Society, 2013)
We report on light-sensitive nanocrystal skin (LS-NS) platforms composed of monolayer visible nanocrystals (NCs) on top of bilayers of polyelectrolyte polymers. These LS-NS devices are operated on the principle of ...
Highly flexible, full-color, top-emitting quantum dot light-emitting diode tapes
We report flexible tapes of high-performance, top-emitting, quantum dot based, light-emitting diodes (QLEDs) with multicolor emission, actively working even when flexed. The resulting QLED tapes reach a high peak luminance ...
Excitonically driven quantum dot light-emitting diodes: exLEDs
(Optical Society of America, 2013)
A hybrid platform of colloidal quantum dots integrated into conjugated polymers is eported for excitonically driven light-emitting diodes having pure quantum dot emission in the electroluminescence spectrum with substantially ...

Electromodulation of photoluminescence from CdSe nanorods film
(World Scientific Publishing Co., 2007)
We studied photoluminescence (PL) properties of CdSe nanorods integrated in a thin film sandwiched between transparent electrodes to which an electric field applied. Nearly 20 % of PL quenching accompanied with the weak ...
Förster-type resonance energy transfer (FRET): Applications
(Springer Verlag, 2017)
In this chapter, we present several applications of Förster-type nonradiative energy transfer (FRET) related phenomena. In particular, we review light generation and light harvesting applications as well as bio-applications. ...
