Structural and gas sensing properties of NiO thin films deposited by a novel spin coating technique
This study presents the development and application of a novel sol-gel spin coating technique for the deposition of nickel oxide (NiO) thin films on glass substrates. The newly designed spin coating device operates without the need for a vacuum, providing a cost-effective alternative to traditional methods. NiO thin films were prepared using a sol-gel process, with various thicknesses and rotation speeds tested to idealize film quality. Structural and morphological analyses were conducted using X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM), revealing that the 6-layer sample coated at 3000 rpm exhibited the best crystallization and surface homogeneity. Gas sensor tests were performed to evaluate the sensitivity of the NiO thin films to ethanol, NO2, and H2 gases. The results showed that the sensor responded stably and reproducibly over multiple gas exposure cycles. It also demonstrated the potential for reliable gas detection applications.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
