Перспективы развития фундаментальных наук. Т. 2 : сборник научных трудов XV Международной конференции студентов, аспирантов и молодых ученых, 24–27 апреля 2018 г Т. 2 : Химия. С. 279-281Abstract: There is an increased interest to the compounds of the ABPO4 type, activated by europium, where A and В are mono- and divalent cations, because of their luminescent properties. In this paper NaBaPO4:Eu^^phosphors with different europium content were synthesized by SPfS method. It is shown that phosphor surface becomes less alkaline (pHas changes in the interval 10,7-9,5) with an increase in the concentration of an introduced activator (5-12%). Two bands with maxima wavelength of approximately 425 and 490 nm are observed in the luminescent spectra (the positions of maxima differ somewhat in different spectra). The relationship between acid-base and luminescent properties of the investigated phosphor samples is traced.
