Here; we examine the structural; vibrational; optical; and morphological properties of ZnO particles synthesized by the hydrothermal method; incorporating cadmium at different concentrations through the molar ratio Rm = Cd+2/Zn+2 and a thermal treatment at 500°C. The X-ray diffraction results demonstrated the high crystallinity of the ZnO compound with a wurtzite-type hexagonal structure. The Raman scattering spectra demonstrated that the ZnO vibrational modes occur in the region between 200 and 1300 cm-1; which is associated with different vibrational configurations characteristic of the ZnO molecule: E2(Low); E2(M); A1(TO); E1(TO); 2B1(High); E2(High); and TA + LO. The modes that were most affected by the incorporation of Cd2+ were those assigned to 2E2(Low); and; and this effect was associated with a greater displacement of Zn2+ ions. The optical study showed a reduction in the band gap and a decrease in the crystalline quality due to the substitution of Cd2+ in the ZnO lattice. Cadmium incorporation affected the morphology of the ZnO:Cd particles; changing the lengths and diameters of the ZnO rods; when the Cd concentration was increased; the ZnO rods shortened; forming coin-type hexagonal structures. © 2015 The American Ceramic Society;
