Laser-induced fluorescence (LIF) is a non-invasive spectroscopic method in which the atoms or molecules of a sample are excited to a higher energy level by the absorption of laser photons followed by spontaneous emission of light. Spectroscopic analysis of the emitting light provides information of the molecular composition of the target material.
LIF uses UV photons for material excitation in order to get spontaneous fluorescence emission informing on its structural composition.
