Nanofibras en Febrero…

El progreso en el último mes puede ser calificado como 3, logrando %50 de  los objetivos. Hemos logrado una mejor caracterización de las fibras, pero lamentablemente, no he podido hacer otra caracterización que no sea por el SEM. Uno de los experimentos consistió en metalizar la muestra con Paladio y pudimos caracterizar su morfología pero no hemos tenido disponible otros instrumentos para una mayor caracterización.

Abstract:

ZnO/ZnS Fibers Synthesized through a Novel, Low Temperature, Solution Method

Zinc chalcogenides are promising materials for photochemical measurements due to their wide bandgaps and thermal stability. Some applications are found in transistors, solar cells and light emitting diodes. In recent years, different methods for the synthesis of Zn chalcogenide nanostructures have been reported. In this project, ZnO/ZnS nanofibers have been synthesized by solution reaction at 80°C. Reacting Zn2+ cations with hexamethylenetetramine and 1-adamantanethiol produced the fiber-precursor. This precursor was heated to 200°C in vacuum on a silicon substrate to produce the fibers. The results have been analyzed with scanning electron microscopy and electron dispersion spectroscopy, and have been discussed in terms of fiber composition, morphology, and potential applications.
