摘要：

The rare earth complex (Eu(PBA)(3)) with the active functional group (-OH) was prepared by p-hydroxybenzoic acid (PBA) and europium chloride in the ethanol solution. Then, the photoluminescence polyurethane (Eu (PBA)(3)/PU) materials were synthesized by the reaction of the functional groups on the complex with the isocyanates in the polyurethane reaction system. The content of the complex has great influence on photoluminescence performances of Eu(PBA)(3)/PU materials. The fluorescence intensity increases with the increase of Eu(PBA)(3) content. Especially, the obtained Eu(PBA)(3)/PU materials possess good fluorescence emission purity and a long luminescence lifetime, which have potential applications in optical display instruments.
