  "id": "MLC-T-CHM-004187",
  "term": "Excitation-emission spectrum",
  "field": "Chemistry",
  "definition": "A three-dimensional plot or contour map that displays the fluorescence emission intensity as a function of both the excitation and emission wavelengths. It is generated by collecting multiple emission spectra at different excitation wavelengths. This type of spectrum provides a unique fingerprint for a fluorescent substance.",
