Abstract. Free-standing powders of doped ZnS nanoparticles have been synthesized by using a chemical co-precipitation of Zn2+, Mn2+, Cu2+ and Cd2+ with sulfur ions in aqueous solution. X-ray diffraction analysis shows that the diameter of the particles is 23nm. The unique luminescence properties, such as the strength (its intensity is about 12 times that of ZnS nanoparticles) and stability of the...
Abstract. ZnS nanoparticles doped with Ni2+ have been obtained by chemical co-precipitation from homogeneous solutions of zinc and nickel salt compounds, with S2- as precipitating anion, formed by decomposition of thioacetamide (TAA). The average size of particles doped with different mole ratios, estimated from the DebyeScherrer formula, is about 22.5nm. The nanoparticles could be doped with nickel...
