【 摘 要 】

In this contribution, hydrothermal method was used to synthesize ZnSe nanostructures. Effect of different sources of Zn, Se and cetyl tri-methyl-ammonium bromide (CTAB) (cationic) surfactant on the morphology of ZnSe was studied. The prepared nanostructures were characterized using powder X-ray diffraction (XRD) and emission scanning electron microscopy (SEM). The XRD patterns showed that the ZnSe samples have a zinc blende structure. The SEM images demonstrated clearly that the ZnSe nanoparticles prepared with ZnCl2and Zn (acetate)2.2H2O as Zn sources are in spherical and micro rod forms, respectively. Also, the results indicated that the nanoparticles prepared using CTAB surfactant with different types of sources of Zn and Se are spherical. The results demonstrated that the source of Se has no effect on the morphology of ZnSe. The size of nano particles ranging from 10 to 15 nm was estimated by Scherrer’s equation.
