Preparation, characterization and properties of sputtered electrochromic and thermochromic devices

Preparation and Characterization of VO2 Nanopowders

“…This phase transition is associated with abrupt changes in optical and electrical properties; therefore, VO has potential applications, for example, in preparing thermal and optical switches (2,3). Although various technologies have been developed for producing VO "lms (4,5), few convenient ones have been found for making VO powders. The typical method of preparing VO powders is to heat a mixture of V O (or V) and V O corresponding to VO composition in an evacuated silica tube at 7003C for 2 days (6), or to reduce V O powder in a platinum crucible under an inert atmosphere at 1200}13503C for 3 days (7,8).…”

Room temperature NO2 sensing performance of free-standing mesh-structure vanadium dioxide nanorods by a chemical vapour deposition method

“…It was the present of many physical and chemical characteristics [12] during its phase transition that make it get wide attention of scientific researchers. So far, VO 2 can be used in gas sensor [13], rechargeable lithium ion battery [14], smart window [15], fast photoelectric switch [16], and so on.…”

The electrochromic performances of single phase VO2 nanoparticled films

“…Due to their superior properties, V 2 O 5 phase of the vanadium oxide films have been mentioned many times in literature. The usage of vanadium dioxide VO 2 structures is more popular than other VOx forms due to their unique thermochromic properties, polymorphic structures and reversible metal-insulator phase transition (MIT) [9,[12][13][14][15][16][17][18][19]. VO 2 has different phase structures such as rutile VO 2 (R), monoclinic VO 2 (M), VO 2 (M1), tetragonal VO 2 (A), and metastable VO 2 (B), VO 2 (C) [12][13][14][15][16].…”
