Its Optical Property and Characterization of Silver Antimony Sulfide Nanostructured Clusters Synthesized Using a Facile Wet Chemical Route

摘要

Cubic phase of silver antimony sulfide (AgSbS2) nanostructures were successfully synthesized from silver nitrate (AgNO_3), antimony acetate (CH_3CO_2)_3Sb, and sodiumthiosulphate pentahydrate (Na_2S_2O_3-5H_2O) in propylene glycol (PG) without using any surfactants or splitting agents by a facile wet chemical route at 160 °C for 30 min. The XRD, SEM and TEM reveal AgSbS2 nanostructures forming the clusters. Due to the UV-visible absorption shows its direct band gap, is 1.80 eV, AgSbS_2 is found to be the excellent material for the solar energy converters. And the possible formation of AgSbS_2 nanostructured cluster was also discussed.
