Yartsev Group

Research Interests

  • Light induced processes in novel photovoltaic materials and functional solar cells.
  • Role of inter- and intra-molecular relaxations in fundamental chemical reactions.
  • Coherent phonon dynamics for elastic and electric/thermal conductivity characterization of solid-state materials.
  • Combining methods of time-resolved spectroscopy:
    • Transient Absorption,
    • THz Absorption and Emission,
    • Fluorescence/Photoluminescence
    for comprehensive description of fast photo-processes. 

Techniques used

  • Time-resolved photoluminescence (PL)
  • Time-resolved (transient) absorption 
    • Pump: 3.1 – 1.4 eV
    • Probe: 
      • Near UV – near IR 
      • THz: Time-resolved THz spectroscopy
  • PL Quantum Yield (CW and pulsed pump)
