摘要: Abstract Ordered Tb 3+ -doped zinc oxide nanowire arrays embedded in anodic alumina membranes (AAMs) were fabricated by an improved sol–gel method. They are hexagonal wurtzite structures with uniform diameter of about 30 nm. From the Raman spectra, peak at 439 cm −1 (E 2 (high) mode) decreases greatly, even disappears. It is seldom seen ZnO. Compared undoped bulk ZnO, intensity 1005 cm increases greatly and shifts towards low shift doping being increased. No luminescence ZnO or O 3 was found spectra. all indicated that ions did enter into lattice.
