摘　　要：A novel method was developed to fabricate monodispersed nanocomposite SiO2 sphere (200￣400 nm) containing homogeneously dispersed Ag nanoparticles (2￣6 nm). The morphology of inclusion was controlled through the N-[3-(Trimethoxysilyl)Propyl]ethylene diamine. TEM images showed that the silver nanoparticles were doped uniformly in silica spheres. UV-Vis showed that the doped silver nanoparticles have a plasmon resonance absorption band at 433 nm. Also SEM, EDX, XRD analyses were conducted to characterize thus-prepared sam- ples.A novel method was developed to fabricate monodispersed nanocomposite SiO2 sphere （200-400 nm） containing homogeneously dispersed Ag nanoparticles （2-6 nm）.
