A novel approach to the synthesis of CdS1−xSex solid solution at room temperature
چکیده انگلیسی

A novel synthesis of CdS1−xSex solid solution is presented, which is based on the room temperature reaction among CdO(CdCO3, CdCl2), Na2S·9H2O and Se powders. XRD and composition analysis results show that the composition of CdS1−xSex is related to the Cd sources. Namely, CdS0.54Se0.46 has been obtained from CdO precursor, and CdS0.75Se0.25 has been obtained from CdCO3 or CdCl2 precursors. The excess Na2S·9H2O plays crucial role for the formation of CdS1−xSex, by which the solid phase reaction mechanism has been discussed. The optical properties of CdS0.54Se0.46 and CdS0.75Se0.25 were characterized by absorption spectrum and fluorescent spectrum, respectively. The average sizes of particles are about 1.67–2.49 μm by the Ls601-Laser particle analysis instrument measurement.
