摘　　要：以CdO、CdC_3、CdCl_2作Cd的前驱物,分别与Na_2S·9H_2O和Se粉在室温条件下,采用固相研磨法制备CdS_(1-x)Se_x。XRD结果表明,合成产物与Cd的前驱物有关,即以CdO作Cd的前驱物时,得到的产物是CdS_(0.54)Se_(0.46);而以CdCO_3或CdCl_2作Cd的前驱物时,得到的产物是CdS_(0.75)Se_(0.25)。吸收谱(U-3310 Spectrophotometer)和荧光谱(AFS AFS-230E)的测试结果进一步证实了CdS_(0.54)Se_(0.46)和CdS_(0.75)Se_(0.25)产物,最后对室温固相反应合成CdS_(1-x)Se_x的机理进行了探讨。A novel synthesis of CdS1-xSexsolid solution was presented, which is based on the room temperature reaction among CdO（ CdCO3, CdCl2 ）, Na2S-9H20 and Se powders. XRD shows that the composition of CdS1-xSex is related to the Cd sources. Namely, CdSo.54Seo.46 has been obtained from CdO precursor, and CdS0.75Se0.25 has been obtained from CdCO3 or CdC12 precursors. The optical properties of CdS0.54Se0.46 and CdS0.75Se0.25 were characterized by absorption spectrum and fluorescent. Based on the results, the solid phase reaction mechanism has been discussed.
