Elaboration of Luminescent Materials on the Basis of Phosphates of NaZr2(PO4)3-type for Research of Living Systems

Compounds Ca0.5Zr2(PO4)3: Er/Yb, Ca0.75Zr2(PO4)2.5(SiO4)0.5: Er/Yb were synthesized, luminescent properties and biocompatibility were investigated. The synthesis conditions providing homogeneity of the phases and the formation of nano-sized powders were selected. Emission of luminescence was established at λ = 0.525 μm under excitation by infrared radiation source. The vitality of cells (neutrophils) after incubation with developed substances did not decrease.
