Özet

Structural characterizations of wurtzite zinc sulfide (ZnS) nanostructures synthesized by vapour-liquid-solid technique (VLS) were carried out by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) analyses. Spectral dependence of photoluminescence (PL) was also carried out for optical characterization. PL results indicate that the bandgap energy of bulk ZnS which is 3 center dot 68 eV at room temperature changes from 3 center dot 7 eV to 3 center dot 72 eV depending on the size of the structures. We also supported these results by calculating the bandgap energies theoretically with using the infinite potential well approximation for 1D structures.
