The nano-Y2O3 was prepared from YCl3 by the citrate precipitation method. The precursor powders were prepared by 0.1 mol/L YCl3 solution and 0.1 mol/L hydrochloric acid in the presence of 1% surfactant PEG2000, which was dried via an ethanol azeotropic distillation method. The effects of reaction te...
