Effect of Static Magnetic Field on <i>Anchusa-Italica</i>-Doped Pentacene

Abstract

This work is devoted to the influence of magnetized water on dye extracted from Anchusa Italica plant and doped pentacene thin films. The findings resulted in optoelectronic behavior, showing that using magnetized water in the extraction process gives rise to distinct and superior characteristics as compared to using regular water. The Fourier-transform infrared method was used to analyze the structural properties of an Anchusa Italica-doped pentacene thin film. A comparative study on two samples was carried out: the first sample was affected by a static magnetic field and the other one was not. Optical properties including the absorption spectra absorption coefficient, optical energy gap, conventional and refractive factors were investigated by applying ultraviolet-visible spectroscopy ranging from 300 to 900 nm. The estimated band gap edge of the dye/doped pentacene affected with magnetization was reduced from 2.61 to 1.76 eV and converted into the recommended direct band gap to contribute to optical systems. The absorption spectra of the sample with magnetization effect appears to be more efficient than the one extracted using regular water. The power transmission coefficients (indirect to direct) were also affected because of the magnetic extraction procedure. The complex refractive index was used to study the magnetization effect on the resonance mode and transparent indicator. The absorption index was enhanced to 570 nm in the spectrum, whereas there was also a low attenuation coefficient. This is the first time that magnetized sol has been used in dye extraction processes.
