Na3Eu(DPA)3-PC树脂的制备及其发光性能
摘要:
根据稀土有机配合物Na3Eu(DPA)3(DPA:2,6-pyridine dicarboxylic acid)的发光强和热稳定性高的特点,采用加热方法将Na3Eu(DPA)3掺入PC树脂中,制成发光塑料树脂.其发光性能结果表明,Na3Eu(DPA)3掺入PC树脂后,仍保持稀土有机配合物原有的发光特性,制成的Na3Eu(DPA)3-PC树脂复合材料具有良好的发光性能,其发光强度与稀土有机配合物Na3Eu(DPA)3掺入的比例量有关,但没有一定的线性关系.

Preparation and Fluorescence of Sodium Tris(pyridine dicarboxylato) Europate(Ⅲ) Incorporated in Polycarbonate Resin
Abstract:
The strong fluorescence and high thermal stability of sodium tris(pyridine dicarboxylato)europate(Ⅲ), Na3Eu(DPA)3, were used for modification of polycarbonate(PC) resin.The polycarbonate resin composite was prepared at 220℃ for 30 min under stirring.The excitation and emission spectra and thermogravimetric analysis results showed that the prepared Na3Eu(DPA)3-PC composite material retained the fluorescence characteristics and strong red emission of the Eu3+chelate and its fluorescence intensity was found to be increased with increase in the mass fraction of Na3Eu-(DPA)3 in PC resin, but did not in linear relation.
