摘要：

We found that by adding Phen to the Eu3+/TTA complexes. the luminescence intensity of Eu3+ can be increased very much. The Phen is bounded to the complexes and can be found not only in the first coordination sphere. It is an efficient shield against the quenching processes and opens a new IMET channel towards the Eu3+. Concerning the ligands, only the S-1 excited state plays a role in the IMET.
