M. Peres et al. (pp. 1695–1698) characterize the morphological and optical properties of ZnO nanostructures grown by pulsed laser deposition (PLD) on c-sapphire and Si(111), assessing them by SEM, PL and reflection measurements. The SEM images show two main kinds of morphology: high-density nanocolumn and nanocone arrays with preferential orientation perpendicular to the substrate plane. In order to analyse the antireflective properties of the PLD-grown nanostructures, room-temperature wavelength and angle dependent reflectance measurements were performed. The results suggest that these nanostructures act as highly effective broad-band antireflection coatings.
