Phase transformation of nanocrystalline CdS synthesized by solvothermal reaction

Phase transformation of nanocrystalline CdS synthesized by solvothermal reaction

CdS was synthesized by solvothermal reaction of CdCl2.2.5H 2O and (NH2)2CS in ammonia solution at 200°C for 10 h. XRD, TEM and SAED show that the products are nanocrystalline CdS. The phase is 100 % hexagonal (hep) in pure water, gradually transformed into cubic with the increase of NH3 concentratio...
