Sensory properties of vanadium pentoxide films in gaseous media

Abstract

Vanadium pentoxide films are synthesized by pyrolysis. The optimum conditions of heat treatment providing for the effective use of films as gas sensors are determined. The sensitivity of the films to different gaseous media (vapors of ethanol, methanol, and argon) is investigated by measuring the electrical conductivity in the temperature range 300-800 K.

Physical property exploration of highly oriented V2O5 thin films prepared by electron beam evaporation

“…[8][9][10][11][12][13] Dietze et al have illustrated the feasibility of using VO 2 as a potential candidate for photoconductive devices. 14 Apart from these, V 2 O 5 finds applications in sensors, 15 actuators, 16 magnetic applications 17 and fiber optic devices. 18 Furthermore, tuning of thickness, morphology and particle size has a pronounced effect in altering the properties of any material due to the enhanced surface to volume ratio and dimensions.…”

Tuning electronic and magnetic properties through disorder in V2O5 nanoparticles

“…Among vanadium oxides, vanadium pentoxide V 2 O 5 , which has the highest oxygen content 1 , is of paramount importance since its properties are highly sensitive to external factors, so it is used in photocatalysts 2 , chemical actuators 3 , optical fibers 4 , gas sensors 5 – 7 , and electrochromic devices 8 . The structure of V 2 O 5 is best described as an arrangement of square pyramid VO 5 units forming layers, which enables high ion storage capacity for batteries 9 – 12 .…”
