Optoelectronic applications of lanthanide‐doped sol‐gel products and porous anodic alumina
View through CrossRef
Abstract— Recent studies on structures, comprising lanthanide‐doped xerogels embedded in porous anodic alumina, are presented. It is shown that a terbium and europium co‐doped sol‐gel film embedded in porous anodic alumina allows a change in the color of the photoluminescence, from red to green, with a change in the excitation wavelength. The possibility of strong erbium‐related 1.53‐μm emission from yttrium‐aluminium garnets in porous anodic alumina is also demonstrated. Visually, it is revealed that the blue alumina‐related emission is predominant over the red europium‐related emission from the structure xerogel/porous anodic alumina structure. Finally, the birefringence effect of a porous anodic alumina membrane is discussed.
