Exciton creation and annihilation by charges are crucial processes for technologies relying on charge-exciton-photon conversion. Improvement of organic light sources or dye-sensitized solar cells requires methods to address exciton dynamics at the molecular scale. Near-field techniques have been instrumental for this purpose; however, characterizing exciton(More)
Numerical spectra for the dielectric relaxation of colloidal sus-pensions of latex particles in aqueous KCl electrolyte solutions at 25 • C were obtained over a wide range of conditions: 10 ζ potential values evenly distributed between 20 and 200 mV, and 11 κa values evenly distributed in logarithmic scale between 1 and 100. The data were used to determine(More)
