SPECTRAL AND POLARIZATION CHARACTERISTICS OF COUMARIN-6 AND EOSIN-Y IN INTERACTION WITH PROTONATED POTASSIUM POLYTITANATE
Abstract
The interaction of coumarin-6 and eosin-Y with particles of protonated potassium polytitanate (PPT) has been studied by spectroscopic and luminescent methods. It is found that the anisotropy of fluorescence of coumarin-6 and eosin-Y in ethanol solution of potassium polytitanate is higher than in ethanol. This can be explained by the binding of the dyes with PPT particles. Based on obtained absorption spectra extinction coefficients for coumarin-6 (l=460 nm) e=25000 M-1·cm-1 and eosin-Y (l=525 nm) e=36,000 M-1 · cm-1 dyes were determined. It is shown that coumarin-6 and еosin-Y can be used to sensitize the PPT.
