超声法制备硫化铅/二氧化硅核壳结构亚微米粒子

分享到: 分享到QQ空间

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 ......(本文共计7页)       [继续阅读本文]
