    Abstract

    Gradient TiO2 nanotube arrays were fabricated by anodization using an asymmetric electrode configuration. The nanotube arrays thus obtained display a gradually changing distribution of tube diameters and length across the sample plane. The application of the fabricated gradient TiO2 nanotube arrays as optical sensors is also demonstrated. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
