Optical constants and nonlinear calculations of fluorescein/FTO thin film optical system
چکیده انگلیسی

The organic thin films of fluorescein dye were deposited on fluorine-doped tin oxide glass substrate by using low-cost spin coating technique. The surface of the deposited film was characterized by using AFM and X-ray diffraction spectroscopy, which shows that the film is uniform and amorphous. The spectrophotometric study was carried out at the wavelength range of 300–2500 nm. The spectral dependences of the linear refractive index and absorption index were found to decrease as the wavelength was increased. Tauc's plot study revealed that the film shows the direct transition and energy band gap values were found 1.75 eV and 3.55 eV for the thin film and the substrate, respectively. Optical constants were found nearly the same in the higher energy domain (1.0–4.5 eV). Spectroscopic method was employed to study the nonlinear optical susceptibility χ(3)χ(3). The deposited thin film is a promising optical system for new generation of optoelectronics.
