Several perovskite‐type nanosized oxides were prepared via polyol‐mediated synthesis. The crystallinity of the materials was analysed by X‐ray diffraction (XRD). While the “as synthesized” materials are amorphous or show very poor crystallinity, highly ordered materials could be obtained by annealing at 700 °C. Morphology of the materials was analysed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Particle size of the materials lay between 20 and 200 nm.
