Porous anodic alumina matrices covered with spin-on erbium-doped In 2 O 3 xerogel films have been synthesized and investigated by photoluminescence (PL) spectroscopy. At room temperature an emission at 1.54 lm associated with 4 I 13/2 ! 4 I 15/2 transitions of Er 3+ ions has been observed for the ex
