FTIR and UV-Visible Studies in 5(6) Carboxyfluoresceine doped PMMA
The effect of 5(6) Carboxyfluoresceine dye on microstructural and optical properties of the polymer Poly (methyl methacrylate) (PMMA) is studied. The FTIR study shows the appearance of new peaks and shift in bands indicates the interaction of 5(6) Carboxyfluoresceine with PMMA. UV-Visible spectrum shows two peaks around 338nm and 458nm.The corresponding two optical energy band gaps and two activation energy band gaps are observed. These results are understood based on charge transfer complex (CTC) formation.
