Magnetic and optical properties of Co-doped ZnO nanorod arrays
In this study, Zn 1−x Co x O nanorod arrays were deposited on Si substrates by magnetron sputtering followed by the hydrothermal method at 100 °C.

O nanorod arrays were deposited on Si substrates by magnetron sputtering followed by the hydrothermal method at 100 °C. The effects of doping concentration and hydrothermal growth conditions on the crystal structures, morphologies, magnetic and optical properties of the obtained Zn
1−x

O nanorod arrays were studied. Surface characterization showed Zn

Co
x
O nanorod arrays with uniform and dense distributions along the [0001] direction with the hexagonal wurtzite structure. Besides, no impurity phases were detected in Zn
1−x
Co

O nanorod arrays. The room-temperature ferromagnetism of Zn
1−x
Co

O nanorod arrays was detected based upon the high-saturation magnetization of 4.4 × 10
–4
emu/g, the residual magnetization of 1.1 × 10
–4
emu/g and the coercive field of 309 Oe. Furthermore, the photoluminescence (PL) spectra exhibited by the Zn
1−x
Co
x
O nanorod arrays with the luminescence intensity in the ultraviolet region were nearly five times that of the pure ZnO nanorod arrays. With the increase in the Co
2+
doping concentration, the redshift in the ultraviolet emission peaks was observed. The theoretical results presented obvious spin polarization near the Fermi level, with strong Co
3d
and O
2p
hybridization effects. The magnetic moments were mainly generated by Co
3d
and partial contribution of O
2p
orbital electrons. These results indicated that Zn
1−x
Co
x
O nanorod arrays can be used as potential magneto-optical materials. |
