我们采用三种不同方法制备了含稀土化合物的光学树脂.第一种是含稀土甲基丙烯酸盐的透明树脂,第二种是采用直接掺杂法制备的含稀土配合物透明树脂,第三种是采用原位复合法制备的含稀土配合物透明树脂.通过对三种透明树脂的热稳定性、抗冲击性、紫外-可见吸收光谱、红外光谱、荧光光谱及核磁等方面的表征,结果表明获得的第二、第三种透明树脂具有非常好的透明性、发光性和相关物理机械性能,进一步比较三种透明树脂的发光性质发现第三种采用原位复合法制备的含稀土配合物透明树脂最好,这说明原位复合法是一种简便快捷合成透明荧光高分子材料的好方法.

Three kinds of transparent resins were prepared by three different synthesis methods. Sample 1 is transparent resins formed by RE(MA)3 salt polymerizing,Sample 2 is transparent resins containing rare earth(RE) complexes by doping method,and Sample 3 is transparent resins containing rare earth complexes by in situ compo-site method. The transparent resins were characterized by TGA,impact energy,UV-Vis,FT-IR ,1H-NMR and fluorescence spectra. The fluorescence data indicated that the optical resins display intense and narrow-band emission,highly visible transparency,and good mechanics performance in Sample 2 and Sample 3. The photoluminescence intensity enhanced and lifetitne is raised in doping or in situ method after introducing RE complexes into copolymer system,by comparing with RE complexes powder. The fluorescence data revealed that the fluorescence intensity of Sample 3,which synthesized by in situ method,is the strongest among the three samples. It was revealed that the in situ synthesis method,as a novel method,can be quickly and simply employed to synthesize transparent optical resins. Comparing with the resins by doping method,these composite resins possess better luminescent property at the same RE concentration.
