Selective petrol vapour sensor based on an Fe2O3 thin film

Characterization and gas-sensing behavior of an iron oxide thin film prepared by atomic layer deposition

“…SnO 2 and ZnO 2 , iron oxides, either pure or doped, have been investigated for sensor applications by several authors, and promising results have been obtained [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Iron oxide thin film gas sensors have been prepared by, e.g., radio frequency sputtering [5], evaporation [6], chemical vapor deposition [7,8], sol-gel processing [11,12,15], spray pyrolysis [13], and liquid-phase deposition [17].…”

Effect of nitrogen dioxide on the EPR property of lithium octa-n-butoxy 2,3-naphthalocyanine (LiNc-BuO) microcrystals

“…The inadequacy of these sensors is that they require very high working temperatures, usually 300-400°C. To optimize the operating conditions of these sensors, thin-film sensors have been developed [5][6][7]. These films still require temperatures above 100°C.…”

The film-forming behavior on the interface between air and hydrosol of Fe2O3 nanoparticles

“…Metal oxide thin films have widespread applications and some of their preparation methods, such as chemical vapor deposition, sputtering, electron-beam evaporation, pulsed laser deposition, dip-coating, electrodeposition and so on, have been explored [1][2][3][4][5][6] . In recent years, the interests in using Langmuir-Blodgett (LB) technique to construct metal oxide nano-film or organic-inorganic nano-composite film have been growing [7][8][9][10][11][12][13][14][15][16][17] .…”
