abstract = {Tri-doped phosphates Ca8‒xSrxZnSm(PO4)7 with the
β-Ca3(PO4)2 (whitlockite) structure have been synthesized
using solid-state synthesis. The crystal structure evolution
from whitlockite to strontiowhitlockite was observed with
Ca2+ → Sr2+ substitution. X-ray powder diffraction and
second optical harmonic generation methods confirmed the
symmetry inhomogeneity in the series, revealing a change in
space group from to . In the Ca8‒xSrxZnSm(PO4)7 hosts,
Sm3+ ions exhibited intense red emission according to 4G5/2
→ 6H7/2 and 4G5/2 → 6H9/2 transitions, coinciding with
the biological window. The photoluminescence properties were
study in detail, and the most intensive emission was found
in sample with x = 3. All samples from the synthesized
Ca8‒xSrxZnSm(PO4)7 phosphate series showed high viability
rates in aMSCs cell cultures compared to the control. The
samples enhanced the osteogenic differentiation potential of
aMSCs without significant differences depending on the Sr2+
concentration. The antimicrobial activity was study on five
microorganisms: S. aureus, E. coli, P. aeruginosa, E.
faecalis and C. albicans. All phosphate samples effectively
inhibited bacterial growth, with samples x = 6 and 7.5
showing the highest effectiveness. The antimicrobial
activity results from the synergistic effect of Ca2+, Sr2+,
Zn2+, and Sm3+ ions released into the solution at acceptable
pH values. The study shows that both whitlockite and
strontiowhitlockite structures can be considered as
promising materials for bone substitutes, while the addition
of the luminescent active Sm3+ ions will allow their use for
bioimaging.},
