| Özet: | Заглавие с экрана There is an increased interest to the compounds of the ABPO[4] type, activated by europium, where A and B are mono- and divalent cations, because of their luminescent properties. In this paper NaBaPO[4]:Eu{2+}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 (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. |
