Abstract
Zinc stannate and Sn-doped ZnO nanoparticles have been shown to be amenable to a wide range of potential
applications, such as sensing moisture and combustion gases but also in optoelectrochemical applications,
coatings, together with silver as an electrical contact; they play also an important role as interface layers in
polycrystalline solar cells.[1] However, the key-step for the synthesis of these reliable and well defined
materials is to control defects and morphology of the particles as well as to provide a high dispersion of the
doping ingredient (Sn in ZnO) at the nanoscale without incorporation of other impurities. Since this is very
difficult to achieve by conventional mixing procedures we are currently developing novel types of Sn/Zn
heterobimetallic single-source organometallic precursors which are suitable to encode the appropriate particle
composition (Zn2SnO4 or Sn@ZnO), morphology and dispersion of the metal atoms at the nanoscale. Here we
present the first synthesis and characterization of cubane-like heterobimetallic Sn/Zn precursors and their
facile thermal decomposition to the desired materials mentioned above. In fact, compounds with different
chemical composition, morphology and function, as well as the successful application are accessible.[2]
