The shell effect on the room temperature photoluminescence from ZnO/MgO core/shell nanowires: Exciton-phonon coupling and strain
(Institute of Physics Publishing, 2017)
© 2017 IOP Publishing Ltd.The room temperature photoluminescence from ZnO/MgO core/shell nanowires (NWs) grown by a simple two-step vapor transport method was studied for various MgO shell widths (w). Two distinct effects ...
High spectral field enhancement and tunability in core-double shell metal-dielectric-metal spherical nanoparticles
(Royal Society of Chemistry, 2016-11)
In this work we have developed full Mie theory for spherical core-double shell NPs, considering the boundary conditions of the electric and magnetic fields at each interface, to study plasmon resonances, optical extinction ...

Biological synthesis of CdS/CdSe core/shell nanoparticles and its application in quantum dot sensitized solar cells
(Frontiers Media S.A., 2019-07)
In the present work, we report the use of bacterial cells for the production of CdS/CdSe Core/Shell quantum dots (QDs), a complex nanostructure specially designed to improve their performance as photosensitizer in photovoltaic ...
Manipulation of emission energy in GaAs/AlGaAs core-shell nanowires with radial heterostructure
(American Institute of Physics - AIPCollege Park, 2014)
Photoluminescence was studied in GaAs/AlGaAs nanowires (NWs) with different radial heterostructures. We demonstrated that manipulation of the emission energy may be achieved by appropriate choice of the shell structure. ...

The room temperature photoluminescence from ZnO/MgO core/shell nanowires (NWs) grown by a simple two-step vapor transport method was studied for various MgO shell widths (w). Two distinct effects induced by the MgO shell ...
Precisely tailored shell thickness and Ln3+ content to produce multicolor emission from Nd3+-sensitized Gd3+-based core/shell/shell UCNPs through bi-directional energy transfer
(2019-01-01)
Lanthanide (Ln3+)-doped upconversion nanoparticles (UCNPs) have been paid great attention as multiplexing agents due to their numerous uses in biological and clinical applications such as bioimaging and magnetic resonance ...
Synthesis and magnetic properties of cobalt-iron/cobalt-ferrite soft/hard magnetic core/shell nanowires
(IOP Publishing, 2017-05)
A straightforward method for the synthesis of CoFe2.7/CoFe2O4 core/shell nanowires is described. The proposed method starts with a conventional pulsed electrodeposition procedure on alumina nanoporous template. The obtained ...
Methanol and ethanol oxidation on carbon supported nanostructured Cu core Pt–Pd shell electrocatalysts synthesized via redox displacement
(Elsevier, 2014-07)
Six different carbon-supported Cu core Pt–Pd shell (Cu@Pt–Pd) catalysts have been successfully synthesized by the galvanic replacement of Cu atoms by Pt4+ and Pd2+ ions at room temperature and their electrocatalytic activity ...
Exploring the benefits of electron tomography to characterize the precise morphology of core-shell Au@Ag nanoparticles and its implications on their plasmonic properties
(Royal Society of Chemistry, 2014-08)
In the design and engineering of functional core–shell nanostructures, material characterization at small length scales remains one of the major challenges. Here we show how electron tomography in highangle annular dark-field ...
