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

Compounds Ca 0.5 Zr 2 (PO 4 ) 3 : Er/Yb, Ca 0.75 Zr 2 (PO 4 ) 2.5 (SiO 4 ) 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.
