Abstract:
The possibility to play with light at the nanoscale, control its property, mold its flow and concentrate its electric filed in nanometric volumes has led to the arising of a new field of science: nanoplasmonics. This field is constantly growing at a high pace and, along with nanotechnology, is driving the development of next-generation optoelectronic devices. These new research fields have a broad impact from medicine to energy harvesting hence the interest in studying this filed seeking more affordable nanofabrication techniques which will allow the scale-up of plasmonic devices.
This work is dedicated to the nanofabrication, characterization, and application of complex plasmonic nanostructures with engineered optical properties. Large-area and homogeneous asymmetric plasmonic crystals were fabricated combining thermal nanoimprint lithography (top-down) with tilted thermal evaporation (bottom-up) while the merger of nanoimprint lithography and nanoparticle self-assembly have led to the fabrication of long-range homogeneous nanoparticles supercrystals. Both systems have been characterized in order to engineer their optical response and finally tested for surface-enhanced fluoresce and surface-enhanced Raman spectroscopy.
