Electrochromics is a healthy blend of basic physics and chemistry, thin film science, device technology and market opportunities. Use of electrochromic (EC) materials as smart windows in an interactive architecture of buildings provide a better option for energy saving. Hence developments in electrochromics will remain a vital field for endeavors of various kinds in coming years. Molybdnum oxide (MoO3) shows pronounced electrochromism due to its interesting structural(provides conduits for intercalation/deintercalation) and electronic properties. It is a 4d transition metal oxide, which can...
