Nanophases of various compositions have been produced by two different methods, using solar furnaces with high concentration energy flux, in Odeillo - Font Romeu (France): a - vaporisation - condensation (PVD process) in solar reactors; b - melting and fast cooling followed by ballmilling.
Among the series of materials which have been prepared by this way, the presentation will be focused on the preparation of Zr1-xYxO2, Ce1-xGdxO2, -(Bi1-xYx)2O3, which are superionic conductors; Zn1-xInxO, Zn1-xSbxO, Zn1-xAlxO, expected to be optically transparent and exhibiting high densities of electronic carriers, Zn1-xCoxO, which is ferromagnetic as a nanopowder prepared in ad hoc conditions, Zn1-xBixO-( Bi1-yZny)2O3, for its electrical properties. The obtained nanopowders have been characterized by X-Ray Diffraction and Electron Microscopy. They can be used to prepare massive nanomaterials, thin or thick nanostructured films or as obtained, depending on their properties and on the aimed applications: solid electrolyte for SOFC or sensors, transparent electrodes for optoelectronics or photovoltaic cells, luminescent screens, magnetic devices or varistors.
An overview will be presented on the preparation by similar methods of metallic nanoparticles of Zn or Al, as well as the preparation of fullerens, carbon nanotubes and SiOx nanopowders.
