摘要：

Europium complex Eu(DB-bpy)phenCl(3)(H2O)(2) (phen: 1,10-phenatithroline, DB-bpy: 4,4'-di-tert-butyl-2,2'-dipyridyl) was doped in poly(methylmethacrylate) (PMMA) and poly(vinyl pyrrolidone) (PVP). The composite systems with various molar ratios of C=O groups/Eu3+ ions were characterized by photoluminescent (PL) spectroscopy, X-ray diffractometry (XRD) and luminescent lifetime measurements. It was found that Eu3+ ions have more than one kind of symmetrical sites in Eu/PMMA composites and the PL spectra of Eu(III) change with the compositions. However. the composites of Eu/PVP with different molar ratios show similar PL spectra, indicating different influence of matrices on luminescent properties. (c) 2004 Elsevier B.V.
