Applications of plasmon enhanced emission and absorption
(Bilkent University, 2009)The term plasmon-polariton is used to describe coupled modes of electromagnetic waves with electronic plasma oscillations in conductors. Surface plasmon resonances have found profound interest over the last few decades ... -
Boradiazaindacene (Bodipy)-based building blocks for the construction of energy transfer cassettes
(Elsevier, 2009-04-15)Energy transfer cassettes composed entirely of boradiazaindacene (Bodipy) units were designed and synthesized to capture photonic energy and convert it to longer wavelength fluorescence emission. The new energy transfer ... -
Chromogenic and fluorogenic sensing of biological thiols in aqueous solutions using BODIPY-based reagents
(American Chemical Society, 2013)Judicious design of BODIPY dyes carrying nitroethenyl substituents in conjugation with the BODIPY core yields dyes that respond to biological thiols by both absorbance and emission changes. Incorporation of solubilizing ... -
Highly directive radiation from sources embedded inside photonic crystals
(American Institute of Physics, 2003)In this work, we have experimentally and theoretically studied the angular distribution of power emitted from a radiation source embedded inside a photonic crystal. Our results show that it is possible to obtain highly ... -
Liquid-liquid diffusion ‐ assisted crystallization: a fast and versatile approach toward high quality mixed quantum dot ‐ salt crystals
(Wiley-VCH Verlag, 2015)Here, a new, fast, and versatile method for the incorporation of colloidal quantum dots (QDs) into ionic matrices enabled by liquid-liquid diffusion is demonstrated. QDs bear a huge potential for numerous applications ... -
Microstructural defect properties of InGaN/GaN blue light emitting diode structures
(Springer US, 2014-06-28)In this paper, we study structural and morphological properties of metal-organic chemical vapour deposition-grown InGaN/GaN light emitting diode (LED) structures with different indium (In) content by means of high-resolution ... -
Nitrogen incorporation and optical studies of GaAsSbN∕GaAs single quantum well heterostructures
(A I P Publishing LLC, 2007)In this work, the effects of N incorporation on the optical properties of GaAsSbN/GaAs single quantum wells (SQWs) have been investigated using temperature, excitation, and magnetic dependencies of photoluminescence (PL) ... -
Observation of efficient transfer from Mott-Wannier to Frenkel excitons in a hybrid semiconductor quantum dot-polymer composite at room temperature
(American Institute of Physics, 2010-12-29)Efficient conversion from Mott-Wannier to Frenkel excitons is observed at room temperature. The time-resolved photoluminescence shows that the energy transfer rate and efficiency reach 0.262 ns-1 and 80.9%, respectively. ... -
Reordering orbitals of semiconductor multi-shell quantum dot-quantum well heteronanocrystals
(American Institute of Physics, 2012-01-27)Based on self-consistent computational modeling of quantum dot-quantum well (QDQW) heteronanocrystals, we propose and demonstrate that conduction-electron and valence-hole orbitals can be reordered by controlling shell ... -
Resonant nonradiative energy transfer in CdSe/ZnS core/shell nanocrystal solids enhances hybrid white light emitting diodes
(Optical Society of America, 2008)We propose and demonstrate hybrid white light emitting diodes enhanced with resonant nonradiative energy transfer in CdSe/ZnS core/shell nanocrystal solids integrated on near-UV InGaN/GaN LEDs. We observe a relative quantum ...
