Precursor was synthesized by solid-state reaction at room temperature among Y(NO3)3·6H2O, Eu2O3 and C2H2O4·2H2O. Y2O3∶Eu3+ phosphor was obtained by decomposing the precursor for about 2 h. The characteristics of phosphor were investigated by means of XRD, SEM, Nano-zs90 Zeta potentiometer and Fluorescence Spectrophotometer respectively. The results show that single cubic phase Y2O3∶Eu3+ with high purity was produced after calcined at 700 ℃ for 2 h. Its morphology is spherical and the average size of particles is 670 nm. The main emission peak of the phosphor excited at the wavelength of 250 nm UV is at 618 nm. The luminescence intensity increases with the growth of Eu3+ concentration at the beginning, then intensity drops when Eu3+ concentration is beyond 8%.
