摘要: In this article, pure phase metastable wurtzite Cu2ZnSnS4 (CZTS) nanocrystals (NCs) were synthesized by a facile one-pot method. When 1-dodecanethiol (DDT) was used as the solvent, two coexisting CZTS phases (wurtzite and kesterite) found. an increased amount of oleylamine (OAm) added to DDT, kesterite disappeared gradually, as-obtained NCs became smaller more uniform. 0.5 mL OAm added, rice-like obtained. The factors, including OAm, reaction temperature, time, concentration precursors, which influence morphology, size, monodispersity NCs, studied in detail. results showed played important role formation final NCs. Time-dependent experiments performed observe growth evolved from spherical-like Cu2S through rhombus-like intermediate shaped ...
