Laser-induced fluorescence and reflection spectra of red and purple natural dyes on silk cloths

Fluorescence spectra due to nitrogen laser excitation were measured for silk cloths colored with some red and purple natural dyes. Identification of these dyes on silk was made possible by the use of laser-induced fluorescence method, since the respective dyes are characterized by their fluorescence spectra. Moreover, it became possible to identify each dye even on faded cloths in this experiment. Results gained by reflection spectra were compared with those obtained by laser-induced fluorescence method.
