摘　　要：Hexagonal CuSCN and cubic Cu2S micro-scale crystallites have been selectively fabricated using CuCl2·2H2O and KSCN as the starting materials at 30 ℃ and 220 ℃, respectively. The results reveal that the reaction temperature plays a key role in obtaining pure phase of CuSCN and Cu2S crystallites. Nearly monodispersed Cu2S nanocrystals were prepared by introducing surfactant into reaction system. The possible reaction mechanism is also discussed.Hexagonal CuSCN and cubic Cu2S micro-scale crystallites have been selectively fabricated usmg CuC12·2H2O and KSCN as the starting materials at 30 ℃ and 220 ℃, respectively.
