Actual dopant concentrations obtained by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
| Undoped | 10 mol% | 20 mol% | 30 mol% | 45 mol% | |
|---|---|---|---|---|---|
| a Ce (wt %) | 2.78 | 5.94 | 9.32 | 14.18 | |
| b Bi (wt %) | 65.28 | 40.63 | 37.38 | 30.82 | 22.56 |
| c Ce/(Bi + Ce) mol% | 9.26 | 19.16 | 31.07 | 43.60 |
a Ce accounts for the total mass fraction of the sample; b Bi accounts for the total mass fraction of the sample; c the moles of Ce account for the percentage of the total moles of (Bi + Ce).
