Selective Synthesis of Wurtzite CdSe Nanorods and Zinc Blend CdSe Nanocrystals through a Convenient Solvothermal Route

摘要

By simply changing the reactants’ compositions, wurtzite CdSe nanorods and zinc blend CdSe nanoparticles were selectively synthesized through a convenient solvothermal route with the reaction of cadmium nitrate (Cd(NO3)2· 4H2O), hydrazine hydrate (N2H4· H2O), and Se in ethylenediamine (en) at 140°C. Effects of temperature and composition of the reactants were detected and the amount and gaining rate of Se2? ions were found to determine the morphology and structure of the final product.
