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