稀土配合物Eu（DBM）3 phen/聚丙烯复合薄膜的光学性质

Optical Spectra of Thin Composite Eu（DBM）3 phen/Polypropylene Film

制备了Eu（DBM）3phen掺杂的聚丙烯（PP）薄膜复合材料。利用发光光谱技术,分别展示了Eu（DBM）3phen和Eu（DBM）3phen/PP薄膜的稳态光致发光光谱,比较了这两种材料的发光寿命。与纯的Eu（DBM）3phen相比,该复合材料的发光稳定性有较大的提高;观察到了折射率边界对Eu^3 ＋自发辐射速率的影响。

Eu（DBM） 3phen complex were synthesized and introduced into polypropylene （PP）,obtaining the composite Eu（DBM） 3phen/PP film with smooth surface and transparency.Room-temperature spectroscopy and decay dynamics were performed to explore the luminescence properties of Eu （DBM） 3phen and Eu（DBM） 3phen/PP film.The results indicated that the Eu（DBM） 3phen/PP film displays strong characteristic luminescence and interesting decay lifetime of the Eu^3 ＋ ions.Furthermore,the luminescence of Eu（DBM） 3phen/PP film exhibits an improved thermal stability compared with Eu（DBM） 3phen.
