Abstract

The complex of europium with dibenzoylmethane and mixed-ligand complex containing 1,4-diphenyl-1,10-phenantroline is entrapped in SiO2-based sol-gel produced immobilization matrices. The IR spectra, thermochemical behavior, photoluminescence properties of the obtained composites and the influence of the synthetic conditions (composition of the sol, pH, presence of contaminant ions, ageing and films/membrane drying conditions) are studied and some recommendations to synthetic procedure are given..
