Abstract

In this paper we report the synthesis of metal sulfide nanocrystals, (CdS and ZnS), from the thermolysis, between 150 – 300 °C, in a dynamic vacuum, of the novel long chain asymmetric metal dithiocarbamates, bis(N-methyloctadecyldithiocarbamato) cadmium(II) or zinc(lI), [M {S2CN(C18H37)(CH3)}2].

These nanoparticles ‘self-cap’ during preparation. Different size nanocrystals were synthesised, at different temperatures and there was a change in phase from cubic to hexagonal CdS at a decomposition temperature greater than 300 °C.
