11. Unravelling Sensitisation and Quenching Pathways in Lanthanide Luminophores
Sammanfattning : Lanthanide (Ln) ions find use in cellular detection and probing of many analytes, owing to their unique photophysical properties. However, to make the Ln emission efficient, one has to develop a light-harvesting antenna, which is an organic chromophore that absorbs and transfers energy to the Ln. LÄS MER
12. Energy Transfer Processes and Quenching Pathways in Lanthanide Complexes: The Role of Structural Changes
Sammanfattning : Due to their unique magnetic and luminescent properties, trivalent lanthanides (Ln(III)) have been widely utilised in cellular imaging. Ln(III) luminescence is usually sensitized by a light-harvesting ‘antenna’, a chromophore that can transfer the excitation energy to the Ln(III). LÄS MER
13. Synthesis of Biomimetic Systems for Proton and Electron Transfer Reactions in the Ground and Excited State
Sammanfattning : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. LÄS MER
14. Photoinduced Processes in Molecular-Inorganic Materials - Design Strategies for Control of Photophysical and Photochemical Processes
Sammanfattning : Sunlight is the most abundant renewable energy resource on Earth and has the potential to provide our society with clean energy. Despite this abundancy, solar energy corresponds to only a minority of the global energy production. Two major reasons for this are the limited efficiencies of solar cells and the difficulty of storing solar energy. LÄS MER
15. Dynamics of Photoinduced Processes in Dye-Sensitized Nanocrystalline Semiconductor Films--Reactions in the Photoactive Part of the Grätzel Solar Cell
Sammanfattning : The key materials used to convert solar energy into electricity in the Grätzel-type solar cells are dye molecules and titanium dioxide particles attached to each other. The former are similar to those in common products like purple pigments in blueberry juice, while the latter are like sunscreen, white paint, or toothpaste. LÄS MER
