Abstract
Eu(TTA)4C5H5NC16H33 (TTA:1-(2-thenoyl)-3,3,3-trifluoracetate) is encapsulated in Si-MCM-41 modified with N-(3-trimethoxysilylethyl)ethylenediamine. The X-ray photoelectron spectroscopy and UV-visible spectra of the rare earth (RE) complex and the assembly prove that the RE complex is dispersed in the channels of the modified Si-MCM-41. The emission spectrum of the assembly shows only a 5D0 → 7F2 transition. As compared with the RE complex itself, the lifetime of the assembly becomes longer, and its stability under the UV radiation is much better. (C) 2000 Elsevier Science B.V. All rights reserved.
