摘要	A europium complex Eu (DBM)(3) TPPO (Eu tris(belizoylmethide)-(triphenylphosphine oxide)) and silicon nanoparticles have been hybridized. The hybridization can evidently change the photoluminescence (PL) characteristics of the Eu complex in the following aspects: under an excitation of 390 nm, the intensity of the PL peak at 611 nm due to the D-5(0)-F-7(2) transition of the Eu3+ ions has been increased by 30%, and the integrated PL intensity in the visible range has been increased by nearly 3 times; the PL excitation efficiency beyond 440 nm has been improved evidently; the peak in the PL excitation spectrum shifts from 408 to 388 nm, and the PL decay time decreases from 2.07 to 0.96 mus. The experimental results indicate that in the PL process, the photoexcited energy may transfer from the silicon nanoparticles to the Eu3+ ions.
