Abstract: The controllable synthesis of hexagonal flower-like Zn-doped CdSe (Cd1−x Zn x Se, x =0.1) microstructures from the solid air-stable precursor has been achieved by two facile steps: first, precursors were prepared directly through precipitation reactions of stoichiometric cadmium acetate, zinc acetate and sodium selenite in distilled water under ambient condition; second, pure hexagonal phase flower-like Cd0.9Zn0.1Se were produced via solvothermal treatment of the precursor compound in ethylenediamine (en) at 180°C. The products were characterized by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), energy dispersive spectrum (EDS) and UV–vis absorption spectroscopy. It was observed that the optical band gap energies of the as-synthesized flower-like Cd0.9Zn0.1Se microstructures shift toward shorter wavelengths compared with CdSe. [Copyright &y& Elsevier]
