In this paper we reported a NH3·H2O-assisted solvothermal route for successful synthesis of cadmium hydroxyl chlorides (Cd x (OH) y Cl z ) microstructures with different phases and shapes, employing 1D CdQCl (Q=quinoline) complex microwires as the precursor. Experiments contained two processes: firstly, CdQCl complex microwires with 500–600nm in diameter and several hundreds of micrometers in length were prepared by the complexation between CdCl2·2.5H2O and quinoline at room temperature; then, CdQCl microwires were solvothermally treated at 150°C for 10h in the presences of different amounts of NH3·H2O to produce Cd x (OH) y Cl z microstructures with various phases and shapes. The as-obtained precursor and Cd x (OH) y Cl z microstructures were characterized by scanning electron microscopy, transmission electron microscopy, Infrared spectrometry and X-ray powder diffraction. Experiments showed that hexagonal Cd(OH)Cl was obtained from water–methanol system, while rhombohedral Cd4(OH)5Cl3 from methanol system. Also, it was found that the shapes of Cd x (OH) y Cl z could be tuned by the amounts of NH3·H2O. Furthermore, the UV diffuse reflection and photoluminescence spectra of the precursor and Cd x (OH) y Cl z were also investigated. [ABSTRACT FROM AUTHOR]
