Abstract

Picolinic acid:Eu³⁺ complex was formed in SiO₂ xerogels through an in-situ synthesis technique. The complex in SiO₂ xerogels was determined by fluorescence spectra, infrared (IR) spectra, which compared picolinic acid:Eu³⁺ in the xerogel with the complex synthesized in aqueous solution. The energy transfer and thermal stability of the complex in SiO₂ xerogels were also studied. The results showed that, in SiO₂ xerogels, the energy transfer from picolinic acid to Eu³⁺ improves the luminescence intensity of Eu³⁺ by a factor of more than 100 and the complex can exist stable at 400°C. © 1997 Elsevier Science S.A.
