摘　　要：Mixed strontium-yttrium borate phosphor Sr3Y2（BO3）4 doped with Eu^3＋ ions was obtained by the sol-gel Pechini method. Crystal structure of the synthesized compound was analyzed by X-ray powder diffraction. Optimal conditions for the synthesis were found. Photophysical properties of the phosphor samples were investigated by collecting excitation and luminescence spectra as well as measuring lumi- nescence lifetime. Judd-Ofelt analysis showed that Eu^3＋ ions occupied Y^3＋ sites in the crystalline network. The studied compound showed a red emission with the quantum yield of 54%-55% and can be potentially used as phosphor for plasma display panels and luminescent tubes.Mixed strontium-yttrium borate phosphor Sr3Y2（BO3）4 doped with Eu^3＋ ions was obtained by the sol-gel Pechini method.
