波长转换膜的制备及表征

摘要

The rare earth complexes Eu2(TPA) (TTA)4phen2 has been synthesized by hydrothermal method, and the compound was characterized by IR spectrometry. The complex was doped with SiO2 collosol, and coated on K9 glass slides by dipping method,, Preparation is made to the wavelength transform films. The fluorescence of the films were characterized by fluorescence photometer. The results, excitation the films by wavelength of 340 ~410nm,the distinct emission peak was at the wavelength of 600 -620nm,they have good wavelength transform function.%用水热法合成了Eu2(TPA)(TTA)4phen2稀土配合物,通过IR测试对其进行表征.将稀土配合物掺杂到SiO2溶胶中,通过浸渍提拉法在K9玻璃片上成功的制备出高性能的波长转换膜.通过荧光分光光度计对薄膜的荧光性进行表征.结果显示,该薄膜用340～410nm范围内的波长激发,在600～620nm范围内都有较为明显的发射峰,具有良好的波长转换功能.
