Fast processes induced by radiations in condensed matter


Content

1.    Fundamentals of the interaction light-matter; photochromism

  • Absorption and emission processes
  • Mono- and bimolecular radiationless deactivation (energy and electron transfer)
  • Photochromic systems : classes of compounds, reaction kinetics, extension to the solid state
  • Applications to optical data storage and light-driven molecular motions

2.    Ultra-fast processes : sources and time-resolved techniques

  • Introduction, excited states and ultrafast deactivation mechanisms
  • Nano-, pico- and femtosecond laser sources
  • Time-resolved fluorescence spectroscopy
  • Transient absorption spectroscopy
  • Solvent effects
  • Anisotropy effects

3.    Interaction of ionizing radiation and condensed systems

  • Interaction of high-energy photons and matter
  • Interaction of accelerated particles and matter
  • Solvents radiolysis, radiolysis of water and radiolytic yields of radicals
  • Dynamic and reactivity of the solvated electron and radical OH°
  • Applications of radiolytic methods (in nuclear energy, radiotherapy, radical chemistry, polymer synthesis, depollution)

    
4.    Instrumental setups and laboratory training (16h30)

  • Technique of Time Correlated Single photon counting
  • Picosecond electron accelerator
  • Femtosecond laser
