Just add liquid and stir: Dispersions of metal sulfide nanoparticles (CdS, ZnS, PbS, and MnS) can be prepared directly by mixing the corresponding bulk solid with an appropriate ionic liquid, without further additives or solvents (see scheme). The selection of the ionic liquid is critical for the viability of this nanoparticle preparation method.
