Abstract
Ag/ZnO nanocomposites have been synthesized by facile hydrothermal and photodeposition method The effect of different concentration of Ag on the luminous intensity of ZnO was studied The morphology structure and optical properties of Ag/ZnO were investigated by Xray diffraction XRD scanning electron microscopy SEM and photoluminescence PL respectively The XRD patterns show that intensities of diffraction peaks of Ag/ZnO were enhanced The weak diffraction peak at 3828° can be assigned to Ag2O when the concentration of Ag increased to 009 M PL results demonstrate that the UV luminous intensity of ZnO was significantly influenced by the concentration of Ag The UV luminous intensity of Ag/ZnO nanocomposites increased by 11 times as compared with undoped ZnO when the concentration of Ag was 003 M due to the local surface plasma resonance effect of Ag nanoparticles
