Time-correlated single photon counting

  "id": "MLC-T-CHM-012066",
  "term": "Time-correlated single photon counting",
  "field": "Chemistry",
  "definition": "A highly sensitive technique used to measure fluorescence lifetimes by detecting individual photons and recording their arrival times relative to an excitation pulse. This method builds up a histogram of photon arrival times, which directly reflects the fluorescence decay kinetics. It is capable of measuring lifetimes in the picosecond to microsecond range.",
