Laser-induced fluorescence from natural dyes on cloths

Spectra and decay time of fluorescence from dyed cloths were measured under nitrogen laser excitation. The fluorescence spectra and decay time were various for respective dyed cloths. Thus, fluorescence results can be used to identify dyes on cloths. The identification is possible for cloths dyed with a combination of two dyes and for faded cloths. The advantages of the laser-induced fluorescence method are that it is a non-destructive method and can be applied to weak fluorescent dyes.
