Alloyed ternary CdS_xSe_1-x nanorods have been synthesized by the thermal treatment of Cd²⁺ -dispersed polyethylene glycol 2 000 gel (PEG 2000) with ethylenediamine solution of sulfur and selenium   in   a   sealed   system   at   180 ℃ for   24   h,   in   which   the   ratio   of   S   to   Se   in   the   nanorods   was controlled    by  adjusting   the  relative  amounts    of  the  starting  materials.  Based   on   the  results  of experiments, it is found that the CdS_xSe_1-x nanorods were also synthesized with several sulfur sources by the method. X-ray diffraction (XRD) shows that the alloyed ternary CdS_xSe_1-x nanorods are highly crystalline, and no other phase was observed in these nanorods.
