CdSe nanowires (CdSe-NWs) at large scale
were obtained through a simple and clean method. The
reaction was carried out without complexing agents which
often facilitate the preferential nanostructure growth. In
this work, CdSe-NWs with lineal and zigzag shape around
40 and 130 nm in diameter with a wurtzite-type structure
were synthesized. Quantitative EDX analysis indicated the
stoichiometric formation of CdSe, while both HRTEM and
HAADF-STEM analysis ruled out the presence of other
phases such as CdO or nanotubes formation, respectively.
Diameter and length of the nanowires varied with the
reaction time and temperature. This synthesis method
makes the nanostructures purification process easier and
also is non-toxic and its high conversion make it an efficient
method for obtaining CdSe-NWs.
