A New Light for Plasmonics: Synthesis and Characterization of Reconfigurable, Earth-Abundant Plasmonic Nanoparticles
Nanoparticles (NPs) of free electron metals, such as Au, Ag, and Al, have been shown to sustain coherent oscillations of their electron cloud, known as localized surface plasmon resonances, or LSPRs. LSPRs are modulated by the NP's shape, size, and surrounding environment; they lead to wavelength-dependent photon absorption and scattering, as well as a local enhancement of the electric field that can be used in spectroscopy and photocatalysis. Recently, we developed a new partial galvanic replacement approach to synthesize semi-hollow, bimetallic plasmonic structures and discovered how, with an electron beam, we can reversibly and controllably modify their antenna-like properties after synthesis. This discovery offers many opportunities for controlling light localization down to the nanometer level. In this project, the applicant will apply this partial galvanic replacement synthesis to encapsulate and analyze plasmonic NPs and study their reconfigurability, with aim to unravel the underlying mechanism and design principles for the creation of switchable light-matter interactions. Further, the applicant will develop new synthetic routes to incorporate Earth-abundant metals such as Mg, Na, and K, which are predicted to be plasmonic but never studied due to their reactivity.
The minimum academic requirement for admission is an upper second class UK honours degree at the level of MSci, MEng, MPhys, MChem etc, or a lower second with a good Master's, (or overseas equivalents) in a relevant subject.
The studentship provides a maintenance grant at the minimum Research Council UK rate and tuition fees at the UK/EU rate for students who fully satisfy the residence requirements of the UK Research Councils. A fees-only award will be available to EU nationals who are not ordinarily resident in the UK. Students who are liable for fees at the 'overseas' rate are not eligible for these studentships.
