Outline of Final Research Achievements

Fabrication methods of well-dispersed morphology controlled ceramic fine crystals by solvothermal reactions were developed. Nanocrystals of tungsten cesium, vanadium dioxide and Nb-doped titania were fabricated by the solvothermal reaction using ethanol-acetic acid mixed solvent, supercritical water and ethanol, respectively.The products showed excellent visible light transparency and infrared shielding ability. In addition, zinc oxide films consisted with well oriented plate-like crystals were fabricated by the seed-assisted solvothermal reaction. The zinc oxide film formed showed excellent visible light transparency, electrc conductivity and infrared shielding ability.
