We report on a study of structural properties of Zn1-xCoxO by micro- and macro-Raman scattering from phonons. Bulk mixed crystals (x ≤ 0,03), grown by chemical vapour transport were investigated between 5 K and 295 K. Beside the common eigenmodes of the ZnO host lattice, we observed disorder-induced lattice vibration modes and a structure, tentatively assigned to a local vibration mode of the Co impurity. Our results are compared with literature data of other ZnO-based diluted magnetic semiconductors such as (Zn,Mn)O.
