About the Project

Nanotechnology has a myriad of possible applications but further advancement is needed in nanofabrication methods. In this project we will be performing the manufacturing of interesting nanopatterned surfaces using an economical and scalable method called laser interference ablation. Multiple beams of high power lasers will be made to interfere with one another to produce interference patterns containing nanoscale fringes (high and low intensity regions). These interference patterns will be exposed on to surfaces quoted with thin films of luminescent materials, as a result of which nanoscaled patterns will be produced on these surfaces. The process is repeatable, fast and easy. In this project we intend to use such nanopatterned surfaces modified with luminescent metal complexes for optical applications like holography, plasmonics and data storage.

Funding Notes

A scholarship to cover University fees and provide 36 months maintenance at standard RCUK rates (£14,057 for 2015-16 and expected to rise slightly for 2016-17) is provisionally available for applicants who are UK/EU nationals and hold or obtain a minimum of a good (>65%) upper second class or higher integrated UK masters (MSci/MChem) degree or equivalent in chemistry or a related subject. Students with a combination of a good UK or equivalent BSc degree followed by an MSc with >60% in all taught elements will also qualify.
