Structures comprising erbium-doped titanium oxide xerogel/porous anodic alumina show strong photoluminescence at 1.54 lm originating from 4 I 13/2 ! 4 I 15/2 transitions of Er 3+ ions in the xerogel. Depending on the annealing conditions, two phases of erbium-doped titanium oxide xerogel, anatase an
