A convenient method for preparation of pure and doped yttirum oxide was developed, which is based on irradiation of solutions containing yttium nitrate and ammonium formate with UV light or accelerated electrons. Under both types of irradiation, the method yields material with high specific surface area, consiting of spherical nanoparticles 25-100 nm in diameter depending on preparative conditions and post-radiation treatment and with narrow size distribution.
