1. Numerical simulations of ultrafast dynamics in plasmonic nanostructures
University essay from Umeå universitet/Institutionen för fysikAbstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

2. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO
University essay from Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemiAbstract : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

5. Geometry Dependent Optimal Bounds of Absorption and Scattering Cross-section for Small Nanoparticles
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : Light-matter interaction in particles of subwavelength size mostly depends on the size, shape, composition of the particles and relies on the properties of incident light. Henceforth, resonant behavior of light can be effectively controlled by changing the aforesaid geometrical parameters. READ MORE
