      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.},
