- •
The La and Er co–doped BCT–BZT–La–xEr ceramics were prepared at 1250 °C.
- •
Er doped on various substituted sits in ABO3 structure with different contents.
- •
The piezoelectric properties could be improved by adding a small Er contents.
- •
The synergistic effect of La and Er co–doped mechanisms were stated.
