چکیده

cuals2  chalcopyrite  nanocrystalline  are  synthesized  with  facile method.  the  heat  arrested  solvothermal  method  for  synthesize nanocrystalline  were  investigated.  the  time  duration  of  synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters  that we are  studied. the nanoparticles were  synthesized with cucl, alcl3 and  thiourea (sc(nh2)2) as precursors, diehylene glycol  ((ch2ch2oh)2o)  and  polyethylene  glycol  600 (ho(c2h4o)nh)  as  solvent  and  capping  agent  respectively,  and ammonia  (nh4oh) as reducing agent. the parameters of synthesis were  studied  by x-ray  diffraction  (xrd)  for  analysis  of  structure and by ultraviolet–visible  (uv-vis)  spectrophotometer  for analysis of  light  structure.  the  possible  formation  mechanism  metal complexes,  sulfur  ions  and  chalcopyrite  compound  are  also discussed.

Synthesis of CuFeS2 Nanoparticles by One-pot Facile Method

Monodisperse copper-iron-sulfide (CuFeS2) nanoparticles as the infrared light absorbing material (chalcopyrite, 0.65 eV), were synthesized based on facile, one step heating up method, by dissolving of CuCl, FeCl3 and SC(NH2)2 as precursors in oleylamine (OLA) alone or in combination with oleic acid (OA) and 1-octadecene (ODE) as solvent. The phase, size, morphology, and size distribution were c...
