Synthesis of titanium dioxide nanorod arrays using a facile aqueous sol-gel route for ultraviolet photosensor applications

In this chapter, we review the state of the art of aqueous sol-gel route for ultraviolet (UV) photosensor applications based on the nanostructured TiO2. The performance of UV photosensor is associated with the high surface-to-volume ratio, porosity, surface defects, light trapping, and the intens...
