以硝酸镧(La(NO3)3·6H2O)、硝酸铕(Eu(NO3)3·6H2O)、偏钒酸铵(NH4VO3)为原料,以十六烷基三甲基溴化铵(CTAB)为模板剂,用研磨-溶胶-凝胶法制备了三维蚯蚓状LaVO4∶Eu3+介孔材料,并用XRD、XPS、TEM、BET、IR、FL等手段表征了材料的结构、形貌、比表面积、孔径分布及荧光性能.结果表明,在673 K焙烧所得的样品是四方锆石型结构的介孔材料,其比表面积达179.5 m2/g,平均孔径为2.56 nm,孔容积为0.115 m3/g,晶粒尺寸6.38 nm,表现出很强的红光发射(5D0→7F2).适当提高焙烧温度能提高样品的红光发射,但焙烧温度过高(≥1273 K)则破坏材料介孔结构并使其荧光强度急剧降低.
