Abstract

Thermochromic properties of vanadium dioxide (VO₂) have been studied extensively due to their IR reflection applications in energy smart windows. In this paper, we studied the optical switching property of VO₂ thin film, depending on the thermal aging time of the vanadyl acetylacetonate (VO(acac)₂) precursor. We found the alteration of the IR spectra of the precursor by tuning the aging time as well as heat treatments of the precursor. An aging effect of vanadium precursor directly affects the morphologies, optical switching property and crystallinity of VO₂ films. The optimum condition was achieved at the 7 day aging time with metal insulator transition (MIT) efficiency of 50%.
