| Title: Titanium Dioxide Nanorod Array Films for Ultraviolet Sensing Applications | |
| Abstract: In recent years, nanostructured materials particularly in film forms have attracted much attention particularly for optical device applications. The improvement of surface area and the induced confinement effects by the nanostructured materials are believed to significantly improve the device performance. Among of the many beneficial nanostructured materials, titanium dioxide (TiO2) nanomaterials are particularly very interesting to study and investigated to their unique and excellent physical & chemical characteristics. In addition, TiO2 nanostructured materials in nanorod array films have huge potentials for various applications including solar cells and optical sensors. TiO2 nanorod array films exhibit an interesting mixture of multifunctional properties in term of optical, structural, and electrical properties. In this research, these properties were investigated thoroughly to understand the TiO2 nanorod array film characteristics that are suitable for the ultraviolet (UV) sensing applications. In this talk, I would outline our efforts over past few years to fabricate TiO2 nanorod array films using solution immersion method and to develop these nanostructures into UV sensing devices. | |
