Abstract：In the present article, Sr2CeO4∶Dy3+ was synthesized with N,N-methylene bisacrylamide (MBAA) as the net agent. The structure, morphology and luminescent properties were also characterized. It is indicated that Sr2CeO4∶Dy3+ was single-phased without other phase existing and also had good dispersion The UV-visible absorption spectra suggested that the absorption bands were almost at 480 nm. The excitation spectrum for 270 nm emission has several excitation bands; The emission spectrum of Sr2CeO4∶Dy3+ shows two broad bands at 292 and 338 nm under the 370 nm excitation. The effects of Dy3+ doping concentration on the emission spectrum intensity of Sr2CeO4∶Dy3+ were also studied, the results showed that the ratio of yellow emission to blue emission increases with increasing the Dy3+ doping concentration, but with increasing the Dy3+ doping concentration, the emission intensity firstly increased, then decreased, and the maximal emission intensity was at 0.4mol% Dy3+ concentration.
