Abstract
Abstract— This paper summarizes our recent results on the synthesis and investigation of photoluminescence (PL) from lanthanide‐doped microporous xerogel solids mesoscopically confined in porous anodic alumina (PAA). It was demonstrated, for Tb‐doped samples, that the PL intensity is strongly enhanced in comparison to thin xerogel films processed onto flat surfaces and increased with the thickness of the PAA layer. It was revealed for both Tb‐ and Eu‐doped PAA‐based structures that maximum emission is achieved at a excitation wavelength near 285 nm for the employed TiO2 and Al2O3 xerogels. Strong Eu‐ and Tb‐related PL visible to the naked eye was demonstrated, and a method for the fabrication of luminescent images based on anodizing, photolithography, and sol‐gel processes is proposed.
