摘要：

Photoluminescent materials were prepared by introducing lanthanide complexes of 4'-formylbenzo-15-crown-5 (C(15)H(20)O(6)) into a silica matrix obtained by the sol-gel method. The new lanthanide complexes [Ln(C(15)H(20)O(6))(NO(3))(3)(H(2)O)(2)] (Ln(3+) = Sm(3+), Eu(3+) and Tb(3+)) were synthesized and were fully characterised using spectroscopic techniques, and elemental and thermogravimetric analysis. Photoluminescence measurements were performed for the isolated Eu(3+) and Tb(3+) complexes as well as for their related silica based materials. A detailed comparative analysis on the photoluminescent properties of the Eu(3+) complex and of its derived silica material was carried out.
