| 제목 | Fabrication of vanadium oxide thin films from colloidal vanadium oxide (VOx) nanocrystals for smart window applications |
| 초록 | Vanadium dioxide (VO2) has attracted much attention because it is known to undergo a reversible, thermally induced metal semiconductor phase transition. Particularly its optical properties change significantly in the visible and near IR range at its phase transition temperature (TC ~ 68℃). Therefore, this phenomenon can be applicable to smart window applications. We develop solution-phase synthetic routes, to monodisperse, organically functionalized vanadium oxide (VOx) nanocrystals in order to use them as potential thermochromic materials for smart window application. As prepared VOx nanocrystals and their thin film have been characterized by means of TEM, SEM, XRD, FT-IR, XPS and UV-vis-Nir. Results of structural and spectroscopic studies on the formation of vanadium oxide nanocrystals and their thin films as well as the effects of solution compositions and reaction conditions will be discussed together with the optical properties of vanadium oxide thin films. |
