Ionic liquid-assisted preparation of ZnO nanostructures Available to Purchase

Nanostructured ZnO with different morphologies such as rod-like, sheet-like, flowers or mixture of above morphologies have been prepared by hydrothermal route in basic conditions using an ionic liquid (IL): 3-Methyl-1-octyl imidazolium chloride, [C₈mim][Cl] as a structure directing agent. The prepared material is characterized by powder x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high-resolution TEM (HR-TEM). XRD studies show that products are crystallized in the form of wurtzite hexagonal structure. Energy dispersive x-ray spectroscopy (EDX) investigations reveal that the products are extremely pure. The photoluminescence properties evidence the UV- and violet-emitting nature of formed nanostructures depending on the excitation wavelength.
