Structural characterization of SnO2 gas sensing films deposited by spray pyrolysis

The Effect of Various Precursors and Solvents on the Characteristics of Fluorine-doped Tin Oxide Conducting Glass Fabricated by Ultrasonic Spray Pyrolysis

“…This is also in line with another study by Korotcenkov et al (2000), confirming that the presence of (110) and (200) crystal planes depends on the thickness of the coating. Our current study has confirmed this phenomenon; as can be seen in the SEM cross-sectional images on the right hand side of Figure 1., a thick layer of SnO 2 for SnCl 2 .2H 2 O+methanol and SnCl 2 .2H 2 O+ethanol increased from 600 nm to 2.38 μm, while the SnCl 4 +ethanol and SnCl 4 +methanol layer thickness increased from 340 nm to 1.06 m.…”

Deposition and characterization of pure and Cd doped SnO2 thin films by the nebulizer spray pyrolysis (NSP) technique

“…It has also been widely used in devices like sensors for detection of gases [7,8], solar cells [9], and flat panel collectors with spectral selective windows [10]. Researchers investigated a variety of techniques to prepare SnO 2 thin films, such as chemical vapor deposition [11,12], co-precipitation method [12,13], dip coating [14,15], spray pyrolysis [16][17][18][19] and sol-gel method [20,21]. The technique used in this work is known as the NSP technique which is one of the most widely used techniques.…”

Effects of heat treatment on the chemical states of O1s and Sn3d at the surface of SnOx:F films by APCVD

“…The effects of the surface chemical states on the sensitivity [13,14] and electrical properties of SnO 2 films [15][16][17][18] were usually studied with XPS. Kwoka and co-workers [15][16][17][18] investigated SnO 2 thin films exposed to oxygen and hydrogen prepared by the Laser- In this work, X-ray photoelectron spectroscopy (XPS) was carried out to investigate the stoichiometric proportion and the chemical states of all components at the surface of SnO x :F films heated at 700 1C for 202 s and 262 s in a tempering furnace.…”
