铽-丙烯酸聚合物薄膜的制备和谱学性质

以键合方式制备了键合型稀土聚合物－铽－丙烯酸聚合物，通过三维荧光光谱确定了铽在丙烯酸聚合物中的最佳激发波长为306nm，最强发射波长为544nm，Tb-丙烯酸聚合物薄膜在306nm光激发下，产生Tb^3 的特征发射，归属于^5D4-^7FJ跃迁（J＝6，5，4，3）,其最大发射位于544nm，归属于Tb^3 的^5D4-^7F5跃迁，呈现强的绿色发射，说明丙烯酸的聚合没有影响Tb^3 的发光性质，而Tb^3 的参入也没有影响丙烯酸的透明性。通过发射光谱、激发光谱、中红外光谱、远红外光谱和拉曼光谱，研究了铽－丙烯酸聚合物薄膜的荧光性质和谱学性质。

Preparation and Spectroscopic Properties of Terbium Polypropenic Acid Film

The bonding type rare earth polymers polypropenic acid terbium film was prepared through the bonding way. Three dimension fluorescence spectra showed that the optimum excitation wavelength was 306 nm, the strongest emission wavelength was 544 nm. The terbium polypropenic acid film showed the characteristic Tb 3+ emission when excited at 306 nm due to 5D 4 7F J transition ( J =6, 5, 4 and 3). The emission maximum at 544 nm was ascribed to 5D 4 7F 5 transition of Tb 3+ and presented strong green emission. The luminescent properties of Tb 3+ were not affected by polymerism of propenic acid and the transparency of polypropenic acid in visible light region was not affected by the dopping Tb 3+ . The fluorescence properties and spectroscopic properties of the terbium polypropenic acid were investigated by excitation spectrum, emission spectrum, IR, far IR, and Raman spectrum.
