- •
A large quantity of 1D cube-shape CoxZn1−xO nanowires has been fabricated.
- •
Raman spectra of Co-doped ZnO exhibited the feature modes.
- •
The PL properties show that there is an intensive UV multi-peaks emission.
- •
The UV multi-peak emissions exhibit redshift with the increasing temperature.
- •
A U-shaped behavior of the FWHM of the FX-1LO peaks at 10 K–110 K was shown.
