英文摘要: High-quality Zn(x)Cd(1-x)S nanocrystals have been synthesized by mild and facile precipitable-hydrothermal processes using stable, less toxic inorganic salts Cd(Ac)(2), Zn(AC)(2) and Na(2)S as the starting materials. The composition-dependence optical properties of Zn(x)Cd(1-x)S are studied by UV-visible absorption, Raman and photoluminescence spectroscopy. The near band edge luminescence is observed for Zn(x)Cd(1-x)S nanocrystals with relatively narrow full width at half-maximum besides the deep level luminescence of Zn(x)Cd(1-x)S nanocrystals. The linear-dependence of Raman frequency on the composition x indicates the optical phonons of Zn(x)Cd(1-x)S exhibit the one-mode behavior. These Zn(x)Cd(1-x)S nanocrystals with composition-dependent optical properties synthesized by this convenient, cost-effective and easily controllable approach have potential applications in solar cell, photocatalysis, and optoelectric devices, etc. (C) 2008 Published by Elsevier Ltd.
