Optical antenna of comb-shaped split ring architecture for increased field localization in NIR and MIR
(Optical Society of America, 2013)
We propose and demonstrate novel designs of optical antennas based on comb-shaped split ring architecture that display multi resonance field intensity enhancement spectrum. These nanoantennas achieve substantially increased ...
Förster-type nonradiative energy transfer for assemblies of arrayed nanostructures: confinement dimension vs stacking dimension
(American Chemical Society, 2014-02-11)
Forster-type nonradiative energy transfer (NRET) provides us with the ability to transfer excitation energy between proximal nanostructures with high efficiency under certain conditions. Nevertheless, the well-known Forster ...
High-stability, high-efficiency organic monoliths made of oligomer nanoparticles wrapped in organic matrix
(American Chemical Society, 2016)
Oligomer nanoparticles (OL NPs) have been considered unsuitable for solid-state lighting due to their low quantum yields and low temperature stability of their emission. Here, we address these problems by forming highly ...
High-efficiency light-emitting diodes of organometal halide perovskite amorphous nanoparticles
(American Chemical Society, 2016)
Organometal halide perovskite has recently emerged as a very promising family of materials with augmented performance in electronic and optoelectronic applications including photovoltaic devices, photodetectors, and ...
Quantum dots on vertically aligned gold nanorod monolayer: plasmon enhanced fluorescence
(Royal Society of Chemistry, 2014)
CTAB-coated Au nanorods were directly self-assembled into a vertically aligned monolayer with highly uniform hot spots through a simple but robust approach. By coupling with CdSe/ZnS quantum dots, a maximum enhancement of ...
Chiral ceramic nanoparticles and peptide catalysis
(American Chemical Society, 2017)
The chirality of nanoparticles (NPs) and their assemblies has been investigated predominantly for noble metals and II-VI semiconductors. However, ceramic NPs represent the majority of nanoscale materials in nature. The ...
Localized plasmon-engineered spontaneous emission of CdSe/ZnS nanocrystals closely-packed in the proximity of Ag nanoisland films for controlling emission linewidth, peak, and intensity
(Optical Society of America, 2007)
Using metallic nanoislands, we demonstrate the localized plasmonic control and modification of the spontaneous emission from closely-packed nanocrystal emitters, leading to significant changes in their collective emission ...
White-emitting conjugated polymer nanoparticles with cross-linked shell for mechanical stability and controllable photometric properties in color-conversion LED applications
(2011)
We report on the synthesis and characterization of water-dispersible, mechanically
stable conjugated polymer nanoparticles (CPNs) in shelled architecture with tunable emission and
controllable photometric properties via ...
High optical efficiency of ZnO nanoparticles
(IEEE, 2007)
We develop optically efficient photocatalytic ZnO nanoparticles that we chemically embed and well disperse into host PVAc thin films and experimentally demonstrate the highest optical efficiency of ∼70% in ZnO nanoparticle ...
Increased quantum efficiency and reduced red-shift in polymer nanoparticle luminophors
(IEEE, 2008-11)
In this paper, using a polyfluorene derivative, increased fluorescence quantum efficiency and reduced red-shift in the film form of polymer nanoparticle luminophors is achieved, when compared to directly spin coated polymer ...
