Synthesis of copper zinc tin sulphide (Cu2ZnSnS4) with nanoplate morphology was achieved through colloidal method using oleic acid as capping agent and solvent with 1-octadecene (1-ODE) at 240 ℃.X-ray diffraction (XRD) analysis shows that the synthesized nanoplates possessed pure kesterite phase.SEM analysis clearly shows the formation of nanoplates having the size of about 50-100 nm.Electron spin resonance (ESR) spectrum analysis of the prepared nanoplates shows that the valence state of copper (Ⅱ) which indicates the strong coupling with other metal ions.Thermo gravimetric/differential thermal analysis (TG/DTA) analysis shows the weight loss of sample at 450 ℃ predicting the loss of capping ligands on the surface of the nanoparticles.The possible mechanism for the conversion of nanoplate-like structures during synthesis was discussed.The results are discussed in detail.
