[PDF] Synthesis of Chalcopyrite Nanoparticles via Thermal ...

CuInS2 nanoparticles (NPs) have been synthesized via thermal decomposition of metal-thiolate in high boiling temperature solvent. This method does not require toxic, unstable and expensive raw materials. Nearly monodispersed NPs with average diameter ranging from 1.8 to 2.8 nm are obtained. The NPs are found to be compositionally copper rich, Cu:In:S=1.6:1.0:1.3. They exhibit size-dependent ...

Chalcopyrite Nanoparticles as a Sustainable Thermoelectric ...

In conclusion, we have reported the synthesis and characterization of a sustainable chalcopyrite based nanoparticle system for low temperature thermoelectrics. XRD analysis for these samples shows that the nanoparticles exhibit a phase transition from cubic to tetragonal as the amount of iron is increased in the particles. Compositional analysis shows that the particles contain a composition ...
