Abstract The fluorescence spectra of several types of water samples in combination with laser-induced fluorescence (LIF) measurements using 532 nm wavelength excitation source were measured in the laboratory, and the fluorescence matters such as dissolved organic matter (DOM), chlorophyll a (Chl a) and carotenoids were pointed out with spectral fluorescent signature (SFS) technique. It is considered that the peak at 455 nm in the spectrum is contributed by carotenoid(PPC). Finally, the dynamic model of PPC’s fluorescence emission is showed.
