Optical properties of nanopore arrays based on porous alumina — •Hongdan Yan1,2, Dirk Wulferding1,2, Peter Lemmens1,2, Jianmin Shi3, Klaus-Dieter Becker3, Frank Ludwig4,2, and Meinhard Schilling4,2 — 1IPKM, TU-BS, Braunschweig — 2IGSM, TU-BS, Braunschweig — 3IPTC, TU-BS, Braunschweig — 4EMG, TU-BS, Braunschweig
Anodic alumina templates with nanopores show photoluminescence peaks and optical absorption that can be divided into three Gaussian bands. Two kinds of oxygen vacancy centers are responsible for these processes. The defects can be tuned using thermal annealing. Work supported by DFG and B-IGSM.
