Absorption Coefficient

Study of the Optical Properties of Poly Furfuyl Alcohol (Pfa) Doped With Crystal Violet (Published)

Films of Poly Furfuryl Alcohol (PFA) doped by crystal violet have been prepared using casting method, different ratios of (0.01, 0.03, 0.05, 0.07, 0.1)%wt of crystal violet at room temperature (298) K, the optical absorption spectra of these films in the wavelength range from 200-800 nm. The result showed that the optical absorption is due to indirect allowed transitions for pure PFA and different doping ratios, while the Energy gap E_g of the composite films decreases with increasing doping ratios. The absorption coefficient (a), real and imaginary parts (ɛ_r,ɛ_i), and optical conductivity (σ_opt) were found to be increased with increasing the doping ratios.
