“…The average grain sizes of samples 2 and 4 were 9.6 m and 10.1 m, respectively, which were the lowest in all the samples and lower than the data from the literatures for both single La 3+ and single Zr 4+ doped samples. 19,27 The literature 27 presents a two-step sintering method which successfully suppressed the grain size of La 3+ doped Y 2 O 3 to 25 m, however, it is still larger than our data for samples 2 and 4. The small grain sizes in sample 2 and sample 4, especially in sample 2, were attributed to both the low sintering temperature and the small amount of Zr 4+ which could suppress the grain boundary migration.…”

“…This indicated that the La 3+ ions enhanced the mobility of grain boundary while the Zr 4+ ions strongly suppressed the migration of grain boundary, coinciding with the published literatures. 14,17,19,[20][21][22][23] Considering the Y 2 O 3 structure with one fourth of anion sites vacant, 24 the O 2− ions diffuse much faster than Y 3+ ions. Moreover, as profoundly investigated, 23,25 the diffusion of Y 3+ interstitial is ascertained to be the controlling step of sintering process in Y 2 O 3 ceramic rather than Y 3+ vacancy.…”

“…High transparency of Y 2 O 3 ceramics can be obtained at low temperature using La 2 O 3 and ZrO 2 as compound sintering additives. However, systematical investigations of the spectroscopic and thermal properties of Yb:Y 2 O 3 laser ceramics are few reported as so far [23]. Hence, we synthesized the high transparency Yb:Y 2 O 3 ceramics with different Yb doping concentration by vacuum sintering.…”
