Abstract
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:Y2O3 nanopowders by co-precipitation. Nitrate precursors were obtained via a co-precipitation method under different pH values. Yb/Ho:Y2O3 nanopowders were synthesized by sintering at 1 100 °C for 2 h. With the addition 0.5wt%TEOS as a sintering aid, transparent Yb/Ho:Y2O3 ceramics were fabricated by vacuum sintering at 1 700∼1 850 °C for 15∼25 h.
