Optical spectra of nanowires of Cu and Zn chalcogenides.
Nanowires of CuS, ZnS, CuSe, and ZnSe, with diameters in the 5-150-nm range and high aspect ratios, have been prepared with the use of surfactants and characterized by X-ray diffraction and electron microscopy. Electronic absorption spectra and photoluminescence spectra of chalcogenide nanowires have been studied. The spectra show blue-shifts compared with those of bulk samples.
