　　Metal oxide optical materials are nowadays employed in a wide range of applications ranging from biomedical diagnostics to high energy physics, passing through Laser technologies and optical armors. The research increased its recent efforts in order to manufacture materials as bulk single crystals or high optical quality sintered polycrystalline ceramics. At the same time, due to the development of many synthetic routes, materials science is now facing a vivid increase of the variety of materials that might be proposed as suitable for optical applications (such as scintillator and luminescent materials in general) after its incorporation into optical grade polycrystals or other host matrices. In particular, innovative synthesis pathways revealed the ability to easily produce many metal oxide crystals in the form of nanopowders (well below 100 nm). The ultrafine morphology of the nanocrystals brings unique features together with new processing issues, especially concerning light scattering and porosity reduction. Nevertheless, these techniques allow for the realization, at relatively low temperature, of functional inorganic nanocomposites or colloidal crystalline particles of unusual composition, paving the way to the application of materials with extremely high melting point that were so far not accessible with conventional preparation techniques.  

　　This talk will show some recent advances achieved on the preparation, processing and microstructural engineering of macroscopic optical materials and nanocomposites.
