Description: The synthesis of various types of monodispersed,
inorganic nanoparticles can be achieved by well-established procedures.
However the controlled assembly of different types of nanoparticles into
complex and functional nano-systems is still a major challenge. Even the
simplest type of nano-system a "hetero-dimer" consisting of two
different types of nanoparticles; e.g. a semiconductor quantum dot and a
gold nanoparticle - has not yet been realised.
The aim of this project is to find synthesis methods for the mono-functionalisation
of nanoparticles (basically any nanoparticle) and the assembly of
hetero-dimers. Our goal is to synthesise hetero-dimers of gold and
quantum dots as well as two different quantum dots (nano-solar cells).
The project also includes the spectro-electrochemical and morphological
characterisation of the products. The work will build on extensive
preliminary experience of the research group and does involve
international collaborations. The successful candidate will be required
to spend short periods of time overseas undertaking research with
collaborators.
