Carrier density dependence of plasmonenhanced nonradiative energy transfer in a hybrid quantum well-quantum dot structure
(2015)An array of Ag nanoboxes fabricated by helium-ion lithography is used to demonstrate plasmon-enhanced nonradiative energy transfer in a hybrid quantum well-quantum dot structure. The nonradiative energy transfer, from an ... -
Dependence of Photocurrent Enhancements in Hybrid Quantum Dot-MoS2 Devices on Quantum Dot Emission Wavelength
(2019)The spectral dependence of nonradiative energy transfer (NRET) from three spectrally different quantum dot (QD) ensembles to monolayer MoS2 is reported. The QDs with peak emission wavelengths of 450, 530, and 630 nm induce ... -
Influence of graphene oxide/Ag nanoparticle composites on the fluorescence properties of organic dyes
(2017)Graphene oxide/Ag nanoparticle (AgGO) composite materials have been proposed for surface enhanced Raman scattering (SERS) detection of fluorescent dye molecules. In this study we examine the role of the different components ... -
Influence of plasmonic array geometry on energy transfer from a quantum well to a quantum dot layer
(2016)A range of seven different Ag plasmonic arrays formed using nanostructures of varying shape, size and gap were fabricated using helium-ion lithography (HIL) on an InGaN/GaN quantum well (QW) substrate. The influence of the ... -
Methods Development for the Synthesis of Biologically Relevant Porphyrins and Porphyrin Rigid Linker Arrays
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)This research focuses on two main aspects: The synthesis of new derivatives of naturally occurring porphyrins and the preparation of non-natural chromophore-rigid linker conjugates as potential bioisosteres and mimics of ... -
Spontaneous Emission and Energy Transfer Rates Near a Coated Metallic Cylinder
(2014)The spontaneous emission and energy transfer rates of quantum systems in proximity to a dielectrically coated metallic cylinder are investigated using a Green's tensor formalism. The excitation of surface plasmon modes can ... -
A theoretical investigation of the influence of gold nanosphere size on the decay and energy transfer rates and efficiencies of quantum emitters
(2016)We present in this contribution a comprehensive investigation of the effect of the size of goldnanospheres on the decay and energy transfer rates of quantum systems placed close to these nanospheres. These phenomena have ...
