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.
