摘要：

Efficiently luminescent composite fibers of poly (vinyl pyrrolidone) (M-w approximate to 1 300 000) and europium complex Eu(TTA)(3)(TPPO)(2) (TTA is thenoyltrifluoroacetone; TPPO is triphenylphosphine oxide) were prepared by electrospinning, with average diameters of 200-500 nm and lengths of several tens of micrometers. Their photoluminescence properties were studied in comparison to the pure Eu(TTA)(3)(TPPO)(2) complex. It was significant to observe that the thermal stability of photoluminescence in the composite fibers was improved considerably over the pure complex. (c) 2007 American Institute of Physics.
