摘要
One kind of well-defined lead sulfide nano-particles was synthesized according to the literature method and characterized by FE-SEM and XRD. Then, silica-coated lead sulfide submicron particles were prepared with the aid of sonication in a short time. TEM, XRD and XPS were used to observe and analyze the shape and structure of the as-prepared lead sulfide/silica core-shell submicron particles. The results indicate that the lead sulfide nano-crystallines are well coated by amorphous silica with adjustable thickness. After preparation of lead sulfide/silica composite particles, their fluorescence property was further studied.
