Popis:	Self-assembled porous alumina structures (por Al2O3) were prepared by two-step anodization process and characterized by scanning electron microscopy.Filling quasi one-dimensional parallel nanochannels of por Al2O3 host matrixwith iodine guest substance by vapor phase adsorption method resulted inthe formation of I/por Al2O3 nanocomposite. Electrical properties of thesenanocomposite samples were studied by alternating-current measurements ata frequency of 1 kHz. Ellipsometric measurements were carried out in thespectral range 350–1000 nm. Structural transition of iodine species from thechain structures to molecular iodine was found in I/por Al2O3 nanocompositeat ∼ 70 ◦C.
