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

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
Poly [3-(2-methoxyphenyl)thiophene] (PMP-Th) nanowires array was fabricated by electrochemical deposition method using anodic aluminum oxide (AAO) membrane with various diameters as template. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were employed to characterize
