| 摘 要： | 在EA基质中,合成了铽-对氨基苯甲酸配合物荧光剂,红外光谱的分析表明,配合物的吸收峰被EA(EA为双酚A-环氧丙烯酸酯)基质掩盖,表现为EA的特征吸收;荧光激发光谱、荧光发射光谱的研究表明,在EA基质中铽-对氨基苯甲酸配合物已经形成,并且表现出强的铽离子的特征荧光,即发出强的绿色荧光。由此荧光剂制备的光固化荧光防伪油墨在紫外光照射下能发出强的绿色荧光,经固化后的荧光强度明显低于固化前的荧光强度,并讨论了荧光猝灭机理。

| Abstract: | Terbium complex with para-animobenzoic acid was synthesized in-situ in the UV-curing system Bisphenol A epoxy acrylate resin(EA).The properties were studied by FT-IR and fluorescence spectra.The IR results show that the chracteristic IR peaks of terbium complex with para-animobenzoic acide synthesized in-situ are covered by those of EA;The results of fluoresce excitation and emission spectra indicate that the system can emit strong green fluorescence which arrange to the characteristic emission of terbium ion.The system can be used as fluorescent reagent and utilized in VU-curing fluorescent falsification-resistant ink.At last the fluorescent quenching effect of the Fluorescent oil were studied. |
