Project description:

The aim of this collaborative research project is to study the collective optical behaviour of self-assembled nanoparticle arrays and their internal photophysical processes, and to explore their feasibility for plasmon nanolasers and biosensors. The following objectives are planned to be solved: (1) to study how the pattern and symmetry of nanoparticle‘s (NPs) arrays impact the surface lattice resonance (SLR) and introduce methods to enable active tuning of the SLR wavelength; (2) to study the internal photophysical processes of SLRs by comparing NP in arrays versus NPs in solution; (3) to use the SLRs of these self-assembled NP arrays to create a surface plasmon nanolaser; (4) to use 2D plasmonic structures for biosensing applications; (5) to develop alternatives to classical lithographic techniques, employing controlled wrinkling in combination with soft lithography that can be up-scaled to macroscopic areas and is compatible with continuous roll-to-roll processing.
