| Popis: | The possibility to perform chemical reactions inside polymer materials opens a unique opportunity to control and prepare materials for diverse solid-state applications. Based on the affinity of Eu3+ ions for oxygen functionalities, in this work we report the luminescence enhancement of Eu3+ ions inserted in Nafion membranes (Naf/Eu3+) by in-situ complexing to oxalate. The formation of a europium-oxalate type complex enhances Eu3+ luminescence emission, which could be exploited for the construction of devices for oxalate sensing and the fabrication of highly luminescent materials. Possible analytical applications of Naf/Eu3+ membranes were evaluated by fluorescence spectroscopy through the linear response with concentration. The complex formation was followed by infrared spectroscopy and SEM-EDS analysis. |
