Porous nanostructured strontium titanate films doped with europium SrTiO3:Eu 0. 0 5 3 fabricated on silicon and porous anodic alumina by the sol–gel route are presented. The films with the thicknesses of 430 nm and 510 nm after depositions of three and five layers, respectively, have the perovskite structure confirmed by X-ray diffraction. The porous films demonstrate Eu 3 + photoluminescence peaks at 593 ( 5 D 0 → 7 F 1 ), 615 ( 5 D 0 → 7 F 2 ) and 705 ( 5 D 0 → 7 F 4 ) nm. The porosity and PL intensity of the fabricated films noticeably reduce with the number of deposited layers. [ABSTRACT FROM AUTHOR] |
