A mixed solution of yttrium nitrate,ytterbium nitrate and holmium nitrate solution were used as a mother solution,and aqueous ammonia was used as a precipitant to synthesize Yb/Ho:Y_2O_3 nanopowders by co-precipitation.Nitrate precursors were obtained via a co-precipitation method under different pH values.Yb/Ho:Y_2O_3 nanopowders were synthesized by sintering at 1100℃ for 2h.With the addition 0.5wt%TEOS as a sintering aid,transparent Yb/Ho:Y_2O_3 ceramics were fabricated by vacuum sintering at 1700～1850℃for 15～25h.
