Oxides, nitrides, oxynitrides from single source precursors
The development and synthesis of so called single source precursors enables the production of oxide, nitride, oxycarbide and novel oxynitride materials. These organometallic, molecular precursors can be synthesized completely under inert conditions using Schlenk-techniques. Controlled by the composition and the molecular structure of the precursors inorganic materials with different kinds of properties can be formed during heat treatment in inert or reactive atmospheres as well as via solvothermal conversion.
A special research topic is the development of semiconducting oxynitrides with tunable direct band gaps down to the deep UV-region. The use of single source precursors enables the formation of novel metastable, amorphous or nanocrystalline materials as well as crystalline Oxynitride, which can`t by produced by classical powder routes.
Newer Activities are dealing with the synthesis of oxides crystallizing in a perovskite or spinel structure. The use of suitable precursors should lead to materials characterized by innovative properties in the field of optics and optoelectronics for instance.
