Synthesis and Characterization of Bournonite PbCuSbS3 Nanocrystals



Kaya Wei, Joshua B. Martin, James Salvador, George S. Nolas


PbCuSbS3 nanocrystals were synthesized for the first time by a colloidal synthesis route and characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). The particle size of PbCuSbS3 was varied between 5 nm and 200 nm by adjusting the reaction time. The optical band-gap, thermal stability, heat capacity, and magnetic susceptibility of PbCuSbS3 were also investigated. PbCuSbS3 is diamagnetic with an optical band-gap of 1.31 eV and a Debye temperature of 157 K. This study aims to expand and broaden our knowledge of PbCuSbS3 in light of the recent interest in multinary chalcogenides for energy-related applications.
