摘要
Nanocrystalline Cd-doped ZnO has been obtained by hydrothermal synthesis and characterized by powder X-ray diffraction, energy dispersive X-ray spectrum, high resolution scanning electron micrographs and UV-visible diffuse reflectance, photoluminescence and electrochemical impedance spectra. Cd-doping by hydrothermal method decreases the grain size and destroys the microstructure. Although doping does not modify the band gap it suppresses the deep level emission, decreases the charge-transfer resistance and increases the capacitance. Cd-doping enhances the photocatalytic and bactericidal activities. (C) 2012 Elsevier Ltd. All rights reserved.
