Abstract Luminescent lanthanide materials BaMoO4:Eu3+ powders were prepared by chemical precipitation method using ammonium molybdate, barium nitrate and europium oxide as raw materials. Different BaMoO4:Eu3+ powders were prepared by controlling the pH value of solution, changing the sintering temperature and the doping concentration of Eu3+. The BaMoO4:Eu3+ powders were characterized by X-ray diffraction (XRD) and excitation-emission spectra. Experimental results show that a single phase of BaMoO4:Eu3+ can be obtained at solution pH~6, sintering temperature 1000℃ and 8% Eu3+ dopped concentration. The BaMoO4:Eu3+ powders have considerable luminescent intensity, and their excitations take on a double peak structure which locates at ultraviolet (394 nm) and visible blue light (465 nm). The emission is a line spectrum and the main peak located at visible red light (616 nm).
