Abstract
Throughout this research, the impact of Manganese doping on the optical characteristics of ZnO nanolayers was explained. The sol-gel spin coating technique has significant advantages due to the mixing of components on the atomic scale and provides excellent control over the composition that was employed to produce samples. The optical characteristics of Mn: ZnO nanolayers, were determined with the help of UV-VIS-NIR spectroscopy. The linear and nonlinear optical properties of nanolayers were investigated between 300 and 800 nm wavelengths. The dispersion properties of the samples were determined and interpreted in accordance with the single-oscillator model. The third-order nonlinear optical characteristics indicate a good correlation between theoretical and experimental results. These interesting results obtained by Mn-doping of ZnO showed a significant behavior for technological applications in electronic, optoelectronic devices and nonlinear optical applications.
Highlights
Due to their unique properties, optical thin films have been widely used in the automotive industry, medical equipment, communication, computers, optoelectronics, spintronics, biomaterials, energy conversion, data storage, and even architecture [1]
These values show that prepared samples are higher than the values of ZnO thin films studied before and Mn has a significant impact on ZnO thin films and gives better results for nonlinear optical applications
Mn: ZnO thin films were successfully produced with the sol-gel spin coating technique, a simple and effective method
Summary
Due to their unique properties, optical thin films have been widely used in the automotive industry, medical equipment, communication, computers, optoelectronics, spintronics, biomaterials, energy conversion, data storage, and even architecture [1]. ZnO is a suitable material for electronic and optical devices [3]. Developments in the synthesis of high-quality ZnO nanostructures allow the production of semiconductors, especially those used in nanoscale device applications [7]. In the present research, nanostructured doped and pure ZnO films produced by the spin coating technique. The variation of linear and nonlinear optical properties by the Mn doping concentrations of ZnO nanolayers thin films were studied. The solutions were quantified as 0.5 M, 5 ml, and the contents were put into test tubes containing solvent (2-methoxyethanol). These solutions were stirred at room temperature using a magnetic stirrer and an ultrasonic stirrer.
