dc.description.resumo	In this work, Zn2EuxTi1−xO4 and Zn2−xEuxTiO4 (x=0, 1, 2 and 3 mol%) powders were synthesized by complex polymerization method (CPM) and calcined at 1000 °C for 4 h. The powders were characterized by X-ray difraction (XRD), scanning electron microscopy (SEM), UV–Vis spectroscopy in the visible region and photoluminescence properties (PL). The photocatalytic properties were estimated by degradation of methylene blue (MB) dye when irradiated by UV lamps. X-ray difraction results demonstrated the existence of Zn2TiO4 as primary phase and ZnO with secondary phase. According to difractograms, the crystallite size varied between 49 and 67 nm. The Eu3+ ions introduction provides increased absorption in visible region, but the band-gap remains practically constant. In samples were observed an increased in photocatalysis with the increase in europium concentration, while in the Zn2EuxTi1−xO4 samples, photocatalysis was reduced to europium concentrations greater than 1%. Eu3+ doped Zn2TiO4 provided a photoluminescent intensity increasing. CIE chromaticity coordinates confrm emission in the red region of the phosphor	pt_BR
