摘　　要：Single-crystalline Ag_(2)Se complex nanostructures have been synthesized via a solvothermal route in which selenophene(C4H4Se)as a selenylation source reacts with AgNO3 at a temperature of 240°C.An orthorhombic phaseβ-Ag_(2)Se nanostructure was identified by X-ray diffraction(XRD),Raman spectroscopy,field emission scanning electron microscopy(FE-SEM),high resolution transmission electron microscopy(HRTEM),and photoluminescence(PL)spectroscopy.The wettability of the as-synthesizedβ-Ag_(2)Se nanostructure was studied by measurement of the water contact angle(CA).Static water CA values of over 150°were obtained,which can be attributed to theβ-Ag_(2)Se complex nanostructure having a combination of micro-and nanostructures.The superhydrophobic Ag_(2)Se nanostructure may find applications in self-cleaning.Additionally,the photocatalytic activity of the as-synthesizedβ-Ag_(2)Se nanostructure was evaluated by photodegradation of rhodamine B(RhB)dye under ultraviolet(UV)light irradiation.
