摘要：
Fluorescent polystyrene(PS)/porphyrin(TPPA) composite nanospheres were successfully fabricated by electrospinning. The SEM images clearly show that owing to adding TPPA in PS, the averaged diameter of the composite nanospheres became smaller, from 1500 to 580 nm. Fourier-transform infrared(FTIR) spectra determined the chemical composition of the resulting PS/TPPA composite nanospheres. The photoluminescent(PL) spectral analysis indicates that the peak position of the composite nanospheres in either solid state or water is identical to that of pure TPPA, at about 652 nm, and is still unchangeable when they are left for at least 20 d, indicating the stable photoluminescent property of the fluorescent composite nanospheres.
