Abstract
Here we explored a novel and facile electrochemical route for the preparation of Zn 1− x Cd x O ( x is atomic percentage of Cd) nanorods with controllable optical properties. The Zn 1− x Cd x O nanorods can be routinely obtained when the electrochemical deposition was carried out in solution of Zn(NO 3) 2 + Cd(NO 3) 2 + citric acid at −1.0 V (vs SCE). EDS results demonstrated that Cd, Zn, and O elements existed in the deposits, and ternary Zn 1− x Cd x O compounds were obtained. XRD results showed that Zn 1− x Cd x O nanorods were pure ZnO wurtzite structures. HRTEM and SAED analyses confirmed that Zn 1− x Cd x O nanorods were single-crystalline. The optical properties of Zn 1− x Cd x O nanorods were investigated in this paper.
