Enhanced Luminescence of Lanthanides From Xerogels in Porous Anodic Alumina

Abstract

The paper summarizes recently investigated properties of a structure "microporous xerogel/mesoporous anodic alumina", doped with erbium, terbium and europium. An enhancement of green, red and infrared photoluminescence (PL) from the structure associated with intra-transitions of trivalent lanthanides in xerogels is discussed.
