Different thickness of basic fuchsin dye was deposited on conductive FTO substrate by spin coating technique for the first time. Their structural, morphological, linear/nonlinear optical and optical studies were performed. The structural studies confirm the amorphous nature of the studied dye on FTO substrate with original peaks corresponding to the FTO diffraction peaks. The morphological studies suggest the ellipsoid (spherical like) nanostructured of grain size of 235.6 nm and average roughness of 37.188 nm. Optical spectrophotometric studies were used to calculate various parameters like optical band gap, absorption index, and refractive index, dielectric constant/loss….etc. The electrical conductivity and optical conductivity are increased with the photon energy indicates the high absorption of the studied dye. Optical limiting studies were also performed using He-Ne laser of wavelength = 632 nm and solid-state green laser of wavelength = 532 nm. The normalized power is decreasing with increasing the thickness of the films. Our designed material can be used to control the laser power with specified percent for new applications of organic materials.
