Metal/Chalcogenide complexes

Then the chalcogenide ions will combine with the metal ions released from the thiosulfate/selenosulfate complexes, and upon hydrolysis precipitating the corresponding chalcogenides. Due to the differences in the stabihty of the metal-chalcogenide complexes initially formed, the optimal concentrations, pH, and temperatures may vary from one chalcogenide to another. Optimal experimental conditions must be estabhshed for each system. 

The thermoelectric performance of colloidal PbSe films and nanoparticles was studied/ There was ligand exchange by an electrically-conducting SbaTcg metal chalcogenide complex (MCC) to inter-quantum dot electrical conductivity. It was shown that these quantum dots had relatively high electrical conductivities, Seebeck coefficient magnitudes, and thermoelectric performance.
