Substitution mechanism of Zn ions in β-tricalcium phosphate

Zn-doped β-tricalcium phosphate (β-TCP) is synthesized by the solid-state reaction method. The substitution mechanism of Zn ions in β-TCP synthesized here is investigated by carrying out a combination of near-edge X-ray absorption fine structure (NEXAFS) measurements and first-principles calculations. From the results of the present study, the substitution site for Zn ions in β-TCP is successfully determined.
