摘　　要：在正常的实验教学时间内,采用一步燃烧法制备合成铝酸盐为基质、Eu2+为特征发光的发光材料的实验作为材料相关专业本科生或研究生的实验教学内容。对实验所得材料进行了发光性能测试,所得发光体初始亮度达到2500 mcd/m2,在200 min后仍肉眼可见,发射光谱是一宽带谱,波峰位于520 nm左右,样品发蓝绿光,属于Eu2+特征发光。通过对实验内容的设计和所得的肉眼可见的绿色发光材料这一实验结果,不仅让学生学习和验证了发光材料、燃烧合成法等知识,还加强了学生对科研的兴趣,训练了正交试验法。In the normal experiment teaching time,the combustion synthetic experiment of aluminate as matrix and Eu2＋ as characteristic spectrum was designed as experiment teaching content for senior undergraduates or postgraduates majoring in materials or other related. Through the measurement of lu-minous performance,the preliminary luminosity of phosphorescent materials prepared at the favorable conditions is 2500 mcd/m2,and the luminescence after 200 min can also be seen. The emission spec-trum is a broad-band spectrum, the wave mount locates 520 nm and the photic color is blue and green,it belongs characteristic luminescence of Eu2＋. The experimental process helps students to un-derstand the knowledge of luminescence materials and combustion synthesis method, strengthen the students’ interest in scientific research,train orthogonal test method.
