摘要：

The reaction of yttrium acetate hydrate in 1,2-propanediol (1,2-PG) at 300 degrees C yielded the products containing the acetate groups and the glycol moieties. The products decomposed into Y2O3 below 400 degrees C, and the thus-obtained Y2O3 samples had quite large surface areas (>200m(2)/g) and were comprised of crystalline nano-hollow spheres with the outer diameter of 7-18 nm and the inner diameter of 2-8 nm. Dy2O3, Er2O3 and Yb2O3 composed of nano-hollow spheres were also obtained by the glycothermal treatment and subsequent calcination. (C) 2007 Elsevier B.V. All rights reserved.
