Final Activity and Management Report Summary - UOXSSDWA (Ultrafast optical and X-ray studies of solvation dynamics in water and alcohol)
Temperature-dependent terahertz time domain spectroscopy measurements were also carried out on some ionic liquid mixtures containing the iodide-iodine redox couple. It was discovered that beyond a threshold concentration of iodine, new phases appeared between liquid and solid phases that allowed for increased conduction. These phases were found to be consistent with complementary X-ray studies of the melts. These novel results were very important for the fundamental understanding of conduction in room temperature molten salts and for applications where ionic liquids were used as charge transporting media such as in batteries and dye-sensitised solar cells.
