摘要
利用"原位法"合成技术,在EA(双酚A环氧丙烯酸酯树脂)中,合成了稀土荧光配合物Eu(TTA)(AA)2Phen(TTA:噻吩甲酰基三氟丙酮;AA:丙烯酸;Phen:邻菲咯啉),利用红外光谱、紫外-可见光谱和荧光光谱对体系进行了表征。红外光谱的研究表明,配合物在EA体系中的特征吸收峰被基质树脂所掩盖,主要表现为基质树脂的特征吸收;紫外-可见光谱的研究表明,该体系在350nm附近出现配体TTA的强特征吸收,在低于300nm时,吸收峰被基质树脂掩盖;荧光光谱的研究表明,配合物在EA体系中能发出强的铕离子的特征荧光,并且低于铕质量分数为0.4%的范围内,荧光强度与稀土离子含量接近线性关系。
Eu(TTA)(AA)_2Phen complex was synthesized in-situ in the UV-curing system Bisphenol A epoxy acrylate resin (EA). The properties was studied by FT-IR, UV absorption and fluorescence spectra. The IR results show that the chracteristic IR peaks of complex Eu(TTA)(AA)_2Phen synthesized in-situ are covered by those of EA, and UV absorption spectrum results show that the UV absorption peaks at about 350 nm arrange to the absorption of TTA; The results of fluoresce spectra indicate that the system can emit strong red fluorescence which arrange to the characteristic emission of europium ion, and when the content of europium reaches (0.1%), the system can emit intense red fluorescence. the fluorescence intensity is linear with content of europium among (0.2%)^(0.4%).
