In this pepar, the effect of concentration on the fluorescence and absorption spectra of Eosin yin (ethanol, methanol, and DMF) atconcentrations [1×10-4M] and [1×10-5M] was studied. The exctation wavelength of ethanol and methanol was (510 nm), the exctation wavelength of N,N-Dimethylformamide was (530 nm), and some optical parameters such as the absoption wavelength and fluorescence in the UV-Vis and some graphic relationships were measured such as the relationships between the dielectric constant, orientation polarizability (Δf), and the refractive index.
