Eu(TTA)4C5H5NC16H33(TTA:1-(2-Thenoy)-3,3,3-Trifluoracetate) is encapsulated in St- MCM-41 modified with N-(3-Trimethoxysilethyl)ethylene. The emission spectrum of the assembly shows only a 5D0-7F2 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. The emission spectrum of the assembly shows that Eu (TTA) 4C5H5NC16H33 (TTA: 1- (2-Thenoy) -3,3,3-Trifluoracetate) is encapsulated in N- (3-Trimethoxysilyl) ethylene only a 5D0-7F2 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.
