摘要：

In this paper. we report the synthesis, characterization, and Fe(III)-sensing properties of two easily synthesized rare-earth(III)-based emitters, Na3Eu(PDA)(3) and Na3Tb(PDA)(3). Results suggest that the two emitters exhibit high sensitivity and linear spectral response towards Fe(III) (Stern-Volmer constant = 2.21 x 10(4) L/mol, linearity = 0.988). In addition, the two emitters are oxygen- and temperature-insensitive, making themselves promising candidates to be utilized in actual applications. (C) 2009 Elsevier B.V. All rights reserved.
