Selective Synthesis of Wurtzite CdSe Nanorods and Zinc Blend CdSe Nanocrystals through a Convenient Solvothermal Route
Source abstract
Abstract
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.
