Abstract
Nanostructures formed by self-assembly of semiconductor nanoparticles have unique properties that make them useful in various fields. In particular, cadmium telluride is being actively studied in the field 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.
期刊介绍:
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
