Y4Zn4(SiO4)5 silicate doped with Eu3+ ions was prepared by the high temperature solid state method. The phase purity of phosphor series (Y4-xEux)Zn4(SiO4)5 (0.004 ≤ x ≤ 4) was checked by X-ray diffraction. The crystal structure, interatomic distances, and atom coordination numbers of Eu4Zn4(SiO4)5 were determined using x-ray powder diffraction. A study of the luminescent properties of (Y4-xEux)Zn4(SiO4)5 was carried out employing photoluminescence excitation and emission spectra and luminescence decay. The occupied sites of Eu3+ ions, relativ...
