The UV–visible absorption study has been carried out to observe absorbance
of white light by pure FLC and fluorescent dye doped FLC mixtures.
The absorbance in arbitrary unit on the wavelength scale in
nanometer for the pure and fluorescent dye doped has been plotted in
Fig. 5. From Fig. 5 we see that absorbance is higher for fluorescent dye
doped FLC mixtures in comparison to the pure FLC. In fluorescent dye
doped FLC mixtures we see that absorbance is highest for mixture 2 in
comparison to the other two mixtures.
