Time-Lapse Traces of Transformation of CdTe Nanoparticles into Nanowires via Self-Assembly
Abstract
Nanostructures formed by self-assembly of semiconductor nanoparticles have unique properties that make them useful
in various fi elds. In particular, cadmium telluride is being actively studied in the fi eld of solar cells on the strengths of its
long-term stability and low cost. In this study cadmium telluride nanoparticles were synthesized into nanowires in the dark
and their evolutionary process was investigated. Thioglycolic acid was selected from among several thiol-based stabilizers.
A ratio of 1.4:1 (thioglycolic acid to cadmium ion) was used rather than the traditional 2.4:1 ratio. In this study, nanowires
were prepared by self-assembly of nanoparticles and the process of forming straight nanowires was observed. Synthesized
nanowires were observed by using a scanning electron microscope and a transmission electron microscope, and the synthesized
nanostructures were characterized. The wavelength of photoluminescence was converted from 549.9 nm to 553.3 nm
as nanoparticles transformed into nanowires in an aqueous solution. The nanowire solution did not precipitate even after
60 days. The suggested synthetic procedure thus provides a viable pathway for the fabrication of nanomaterials.
