|abstract: ||A chemical method to coat submicron silica particles with nanocrystalline zinc sulfide is described.
The ZnS nanocoating was obtained by the thermalysis of zinc diethyldithiocarbamate in the presence
of morphologically well defined silica particles. The powders obtained were isolated and were
characterized by UV/visible optical reflectance, scanning electron microscopy (SEM), transmission
electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron microscopy (XPS).
The results showed that the silica surfaces became homogeneously coated with ZnS as the reaction
time was increased. This coating consists in clusters of small ZnS particles whose dimensions
are within the nanometric range.|
