Abstract: Photo-absorption properties of Co implantation in rutile TiO2(110) have been investigated. Nearly five times enhancement in absorbance of visible light and 1.7 times increase in UV light have been observed. Formation of crystalline CoTiO3 and Ti1−xCoxO2 phases at high and low fluences, respectively, demonstrates a crucial role in increasing the photo-absorbance, especially in the visible regime. Ti-rich nanostructures and Ti3+ vacancies that develop after ion implantation also reveal significant contribution in these observations. These Co implanted rutile TiO2 surfaces will be useful for visible light photo-catalysis. © 2016, Springer-Verlag Berlin Heidelberg.
