Nanograined (grain size 10 nm) ZnO films with various Co contents (0–52 at.% Co) were synthesized by a novel liquid ceramics method. The solubility limit for Co was determined at 550 °C. The lattice parameter c of the ZnO-based solid solution with würzite structure ceases to grow at 33 at.% Co. The...
