Synthesis and Characterization of Fluorescent PolyoxometalateNano-/Microrods

摘要

Fluorescent nano-/microrods of the polyoxometal ate (POM) K_4H[Eu( α-SiW_(11) O_(39))-(H_2O)_2] 17H_2Owere obtained in aqueous solution by a conventional synthesis method. Thenano-/microrods have been characterized by elemental analysis and FT-IR, UV/Vis, and TG-DTAdata, and their morphology was examined by ESEM-FEG, showing that the average ratio of diameterto length is 1 : 20.The obtained nano-/microrods exhibit a regular profile and an intense fluorescence.
