Fabrication of anodic aluminum oxide with incorporated chromate ions

► Anodic aluminum oxide was formed by anodization in 0.3 M chromic acid. ► Influence of operating conditions on chromate anions incorporation was studied. ► Photoluminescence of anodic alumina with incorporated chromate ions was studied. ► Qualitative arrangement analysis of pores was done. ► an influence of operating conditions on nanopores geometry was investigated.
