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Eu3+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 Eu3+ ions. Furthermore,the luminescence of Eu-(DBM)3phen/PP film exhibits an improved thermal stability compared with Eu(DBM)3phen.
