摘　　要：以铝酸锶为基质材料,用燃烧法与溶胶凝胶法,两种还原方法制取了掺杂铕的发光材料,并对其不同方法制取过程中的条件及对掺杂稀土激活剂的材料的发光性能进行了对比研究.制备出的SrAl2O4:Eu2+(CO(NH2)2还原)/Eu2+(H2还原)发光材料属于SrAl2O4单斜晶系晶体结构;激发光谱是位于峰值335,370 nm的宽带谱;发射光谱是峰值位于510,556 nm的宽带谱.Strontium aluminate was used as matrix material to make luminescence materials doped with Eu by burning and sol-gel method. The difference in the luminescence properties between the two methods was studied. The SrA1204 ： Eu2＋ （ CO （ NH2 ） 2 reduction） / Eu2 ＋ （H2 reduction） luminescence material belongs to monoclinic crystal structure; its excitation spectrum is a broadband spectrum located in 335 and 370 nm, and its emission spectrum is located in 510 and 556 nm.
