Plasmonic nanoparticles have very large absorption cross sections and can concentrate the local density of photon states on the nano scale. When they are coupled to molecules or semiconductor nanocrystals and form different hybrid nanostructures, various light-matter interaction processes can be significantly enhanced or manipulated, including optical responses like fluorescence...
The unique ability of plasmonic nanoparticles to localize and enhance resonant electromagnetic fields has enabled a wealth of discoveries from enhanced spectroscopies to driving chemical reactions on the nanoscale. In this thesis, we strive to both drive and observe chemistry on plasmonic surfaces. First, we examine the possibility of driving...
Characterizing the interaction of light and matter has become increasingly important in recent decades, as devices scale down, data transfer speeds up, and the use of photon-based technology (photonics and optoelectronics) becomes widespread. Copper chloride (CuCl) thin films and zinc oxide (ZnO) inverse opal photonic crystals are the two material...
Metallic nanostructures are able to confine and manipulate electromagnetic fields because light can couple to free electron oscillations called surface plasmons (SPs). These plasmons exist on metal surfaces as localized (short-range) or as propagating (long-range) modes depending upon the size and geometry of the nanostructure. This dichotomy is primarily an...
