Полифункциональные химические материалы и технологии. [Т. 1] : материалы Международной научной конференции, 22-25 мая 2019 г Т. 1. С. 106-108Abstract: There is an increased interest to the compounds of the ABPO4 type, activated by europium, where A and B are monoand
divalent cations, because of their luminescent properties. In this paper NaBaPO4:Eu2+phosphors with different
europium content were synthesized by SHS method. It is shown that phosphor surface becomes less alkaline (pHiis
changes in the interval 10,7–9,5) with an increase in the concentration of an introduced activator (3–15%). Two bands
with maxima wavelength of approximately 440 and 465 nm are observed in the luminescent spectra (the positions of
maxima differ somewhat in different spectra). It is found the presence of two luminescence cites for NaBaPO4 series of
phosphors, which are Eu2+ ions in the NaBaPO4 crystal lattice in positions with coordination numbers 10 and 12. The
relationship between acid-base and luminescent properties of the investigated phosphor samples is traced.
