【 摘 要 】

By means of pulsed electron beam evaporation in vacuum Gd2O3 amorphous nanopowder was produced with a specific surface area 155 m^2/g. The powder consisted of agglomerates of size from tens up to several hundred nm and aggregates formed of amorphous-crystalline particles of near spherical shape and size of 3-10 nm with very narrow size distribution. Magnetic and luminescent properties of the powder were measured at room temperature. Phase transformations in the powder are studied at heating to 1400°C. The amorphous phase Gd2O3 was thermally stable up to temperature of 1080°C.
