Multiple band light trapping in ultraviolet, visible and near infrared regions with TiO_2 based photonic materials

摘要

TiO_2 based photonic materials TiO_2 PMs) with hierarchical top-nanonet/ bottom-nanotube structures were fabricated by a facile two-step electrochemical anodization method. The TiO_2 PMs demonstrated multiple band light trapping activity not only in the ultraviolet and visible regions, but also in the near infrared region.
