摘要：

Silica-based composite materials incorporated with sodium tris(pyridine dicarboxylato) europate(III), SiO2 : Na3Eu(DPA)(3), where H(2)DPA is 2,6-pyridine dicarboxylic acid, were prepared by a sol-gel method. Photoluminescent properties of SiO2 : Na3Eu(DPA)(3) composite were studied after heat treatment between room temperature and 600degreesC. The strong red emission of SiO2 : Na3Eu(DPA)(3) was intensified by heat-treatment under appropriate conditions. The thermal stability of Na3Eu(DPA)(3) . 9H(2)O and its silica-based composite was examined. The results demonstrate that SiO2 : Na3Eu(DPA)(3) composite material possesses very good thermal stability with intense visible fluorescence, and may be applied as a potential luminescent material.
