1. Spin-Orbit and Spin-Spin Coupling in the Triplet State
Abstract : The underlying theory of “Spin” of an electron and its associated inter-actions causing internal fields and spectral shift to bulk-magnetism iswell established now. Our understanding of spin properties is significant andmore useful than ever before. READ MORE

2. Photon Upconversion through Triplet-Triplet Annihilation: Towards Higher Efficiency and Solid State Applications
Abstract : The sun is the only renewable energy source that can accommodate humanity’s energyneeds today and in the foreseeable future. The sunlight reaching the planet’s surfaceis filtrated through the atmosphere, reducing its UV-light intensity in the 300-400 nmrange, which indeed can be harmful to life as we know it in too large doses.

3. Synthesis and Photophysical Characterization of Annihilator-Sensitizer Pairs for Triplet-Triplet Annihilation Based Photon Upconversion
Abstract : Transitioning to a future society, independent of fossil fuels, will denitely require the use of solar radiation for power and fuel production. Due to energy mismatch betweendevice absorption and the broad band irradiation provided by the sun there are severe limitations to how efficient devices for direct conversion of solar radiation can be.

4. Systematic Studies of Triplet Annihilating Species for Photochemical Upconversion
Abstract : With climate change already setting new temperature records and causing more extreme weather events, transitioning to clean and renewable energy sources is more urgent than ever. Solar energy harvesting arguably holds the most promise with the abundance of terrestrial sunlight available. READ MORE

5. Using Low Energy Light to Enable High Energy Photochemistry
Abstract : Manipulating light to meet human needs is pivotal in various research fields and technological applications, ranging from solar energy conversion to photodynamic therapy and fluorescence imaging of cells and tissues. This thesis addresses the spectral mismatches between available light and the specific energy requirements of target photochemical reactions by employing low-energy light to control high-energy photochemistry.
