Abstract

In this work, we investigate europium-containing sol-gel derived films fabricated onto porous anodic alumina (PAA) of thickness ranging from 0.5 to 5 μm. The sols were prepared from Ti(OC₂H₅)₄ precursor mixed with aqueous-alcohol solution of europium nitrate and deposited onto PAA. The concentration of europium oxide in xerogel was 40 wt.%. The PL spectra exhibit bands typical for Eu³⁺ corresponding to ⁵D₀→⁷F_j (j=1-4) electron transitions with the maximum at 617 nm (⁵D₀→ ⁷F₂). The PL intensity of all the bands increases with the thickness of PAA. The samples exhibit a red light emission visible to the naked eye within the investigated temperature range from 10 to 300 K.
