Supramolecular luminescent hydrogels based on β-amino acid and lanthanide ions obtained by self-assembled hydrothermal reactions†
Abstract
Using the hydrothermal method, we obtained new hydrogels based on lanthanide ions and iminodiacetic acid. The hydrogels of europium and terbium show reddish and greenish luminescence, respectively. A mixed Eu–Tb gel system was prepared and the luminescent properties were studied.
