Abstract: EU(TTA)(4)C5H5NC16H33 (TTA:1-(2-Thenoy)-3,3,3-Trifluoracetate) is encapsulated in Si-MCM-41 modified with N-(3-Trimethoxysilethyl)ethylenediamine. The emission spectrum of the assembly shows only a D-5(0)-->F-7(2) transition. As compared with the rare earth complex itself, the lifetime of the assembly becomes longer and its stability under the UV radiation is much better.
