| Title: Fabrication of Ultraviolet Sensors Using Titanium Dioxide Nanorod Array Films and Their Composite | |
| Abstract: In recent years, nanostructured materials, specifically in the form of films, have garnered a lot of attention, particularly for applications involving optical device technology. It is believed that the performance of the device will significantly improve as a result of the increase in surface area as well as the induced confinement effects brought about by the nanostructured materials. Titanium dioxide (TiO2) nanomaterials stand out among the many useful nanostructured materials because of the exceptional and one-of-a-kind physical and chemical properties they possess. As a result, studying and researching these nanomaterials is particularly interesting. Additionally, TiO2 nanostructured materials in nanorod array films have a significant amount of potential for a variety of applications, such as solar cells and optical sensors. TiO2 nanorod array films display a fascinating combination of multifunctional properties, including structural, optical, and electrical properties. In this research, these properties were looked into in great detail in order to gain an understanding of the qualities of the TiO2 nanorod array film that make it appropriate for applications involving ultraviolet (UV) sensing. In this talk, I will provide an overview of our efforts over the past few years to fabricate TiO2 nanorod array films and their composite using the solution immersion method and to develop these nanostructures into UV sensing devices. These efforts have been focused on developing these nanostructures into devices that can detect UV radiation. | |
