Photoluminescence excitation (PLE) spectra for the emission wavelength 1.54
μm were studied for erbium-doped xerogels embedded in artificial opals and porous anodic alumina films. Opals were chosen with photonic stop-band in green spectral range, where excitation of 1.54
μm occurs most efficiently. In comparison to the structure erbium-doped titania xerogel/porous anodic alumina/silicon the photoluminescence excitation spectra for 1.54
μm emission wavelength significantly changes for the same xerogels embedded in artificial opals. Enhancement of erbium-related 1.54
μm emission was observed from the structure Fe

3 xerogel/porous anodic alumina fabricated on silicon, having some incompletely anodized aluminium, under excitation with either the lasing source at 532
nm or xenon lamp. Evident difference in PLE spectra for erbium doped TiO
2 and Fe

3 xerogels in porous anodic alumina is observed.
