Chromium containing zinc oxide materials from organobimetallic precursorst

摘要

Zinc oxide has become one of the most important semiconductor materials and it possesses a multitudeof properties and applications. An even wider spectrum of properties can be envisioned if an additionalelement is introduced. On the cation side there is large interest in the combination of ZnO withparamagnetic metal centres like Cr~(III). Two new single source precursors containing "ZnO" andchromium in the ratios 1 : 1 and 1 : 2 are presented. Advantages and disadvantages of using theseprecursors are reported. One of the advantages is that the geometric organization of the magneticcentres in the ZnO matrix can be preorganized on the molecular scale.
