Abstract
A self-organization of chemical bath deposited cadmium sulfide
colloidal particles into well shaped hexagonal prisms of
nearly the same size in a micrometer range is found. The selforganization
phenomenon itself and the size of resulting
prisms depend on the chemical affinity of the deposition reaction.
In spite of the nearly perfect shape, the inner structure of
the CdS colloidal crystals is highly disordered and has at least
two hierarchy levels. On the scale of scanning electron microscopy,
the loose and disordered microstructure of the colloidal
crystals consists of nonuniformly shaped coagulates,
with sizes between 150 and 250 nm. Transmission electron
microscopy shows that the coagulates are polycrystals with
large angle boundaries between nonuniformly shaped grains
with an average size of 7 ± 2 nm.
