Synthesis and Characterization of a Novel Phase Change Luminescence Materials

Abstract

In this study, a novel phase change material was prepared by coordinating rare earth Tb3+ions to the carboxylate groups of a poly (ethylene glycol).The properties of the material were characterized by differential scanning calorimetry (DSC), infrared spectroscopy (IR) and fluorescence spectroscopy. The synthesis and characterization a novel phase change luminescent Tb-PEG/SA material were described in this paper. The result show that this modified PEG material show both good phase change properties and excellent luminescent properties.
