Thin films of colloidal CZTS nanocrystals (NCs) synthesized using a “green” approach in water with variation the copper-to-tin ratio are investigated by Raman scattering, mid-infrared (molecular vibrations) and near-infrared (free carrier) absorption, X-ray photoemission spectroscopy (XPS), electrical conductivity, conductive atomic force microscopy (cAFM). We determined effect actual Cu conten...

The synthesis of (Cu,Ag)-Zn-Sn-S (CAZTS) and Ag-Zn-Sn-S (AZTS) nanocrystals (NCs) by means “green” chemistry in aqueous solution their detailed characterization Raman spectroscopy several complementary techniques are reported. Through a systematic variation the nominal composition quantification constituent elements CAZTS AZTS NCs X-ray photoemission (XPS), we identified vibrational IR fingerpr...
