Synthesis and characterization of monodispersed ZnS:Ag colloids

摘要: Abstract The homogeneous coprecipitation of ZnS:Ag2S via the hydrolysis thioacetamide (TAA) was investigated. effects silver content and gas/liquid interfacial area per unit liquid volume on particle size number concentration were specifically studied. In general, resulting precipitates are spherical have narrow distributions. Particle growth rate found to be dependent content. On other hand, increases with increasing gas—liquid contact volume. We also observed that actually composed very small crystallites or fibers, depending TAA/[Zn2+] ratio. A formation mechanism corresponding our observation therefore proposed.
