Abstract
Porous nanostructured strontium titanate films doped with europium SrTiO3:Eu[Formula: see text] fabricated on silicon and porous anodic alumina by the sol–gel route are presented. The films with the thicknesses of 430[Formula: see text]nm and 510[Formula: see text]nm after depositions of three and five layers, respectively, have the perovskite structure confirmed by X-ray diffraction. The porous films demonstrate Eu[Formula: see text] photoluminescence peaks at 593 ([Formula: see text]), 615 ([Formula: see text]) and 705 ([Formula: see text])[Formula: see text]nm. The porosity and PL intensity of the fabricated films noticeably reduce with the number of deposited layers.
