abstract Novel luminescent materials were prepared by introducing a new Eu3+ complex of 2,6-dihydroxybenzoic acid (2,6-H(2)dhb) into a silica gel made by the sol-gel method. The crystal structure of the resulting complex [(Bu4N)-Bu-n](2)[Eu(2,6-Hdhb)(5)(H2O)(2)] was determined using single-crystal X-ray diffraction. The compound was further characterised using FTIR, FT-Raman and elemental analysis. Photoluminescence measurements were performed for the isolated Eu(III) 2,6-dihydroxybenzoate complex and also for the related silica composite material. (C) 2003 Elsevier B.V. All rights reserved.
