【摘要】 以钼酸铵、硝酸钡和三氧化二铕为原料,通过化学沉淀法制备稀土掺杂的发红光材料BaMoO₄:Eu³⁺,并用X射线衍射和激发发射光谱对粉体的结构和发光性能进行了表征。结果表明,获得最强发光BaMoO₄:Eu³⁺粉体的最佳合成条件是:反应溶液的pH值为6、烧结温度为1000℃以及Eu³⁺掺杂量（mol分数）为8%。BaMoO₄:Eu³⁺粉可被394 nm的紫外光和465 nm的可见光有效激发,其发射光谱在616 nm处发光强度最大,是以电偶极跃迁⁵D₀→⁷F₂为主导地位的红光发射。更多还原

【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）.更多还原
