Recent advances in aerosol generation of materials are reviewed. Gas-to-particle and spray processes (spray pyrolysis) for powder generation and various routes for film generation are discussed from the experimental and theoretical perspectives. The range of materials generated by these routes has increased in recent years to include fullerenes and ceramic superconductors. Many metals and various oxide and nonoxide ceramics have also been added to the list of materials generated by gas-phase routes. Established aerosol routes such as vapor condensation have found widespread applications for generation of nanophase materials. The formation of quantum dots via aerosol approaches has also been demonstrated. The theoretical understanding of gas-to-particle conversion routes has advanced to include the finite rate of particle fusion or sintering occurring after collisions of particles. The modeling of spray pyrolysis systems has provided insight into the control of particle morphology and reactor design. In this review, these recent developments in aerosol generation of powders and films via gas-phase and spray routes are discussed with an emphasis on the material chen~istries involved and the synthesis of nanophase materials.

“…After 10 min of heating, the substrates were removed and immediately sprayed with the SnCl 4‚5H2O/ methanol solution using O2 as carrier gas. Further heating of the spray-coated films 3,7,11,22 at 500 °C for 1 h was sometimes needed to burn out residual hydrocarbons from the spray solution.…”

“…Tin oxide materials are used in a variety of applications as antistatic films, thin film resistors, and antireflecting coatings in solar cells. Tin oxides have also been investigated as gas sensors for H 2 , O 2 , CO, CO 2 , NO x , H 2 S, CH 4 , C 2 H 5 OH, and C 6 H 6 . − High electrical conductivity, good chemical stability, high transparency (compared to other metal oxides) in the visible region, and strong physical and chemical interactions with adsorbed species are some properties of SnO 2 . SnO 2 is also stable thermally in air at up to 500 °C and mechanically in aqueous media.…”

Tin Oxide Films Made by Physical Vapor Deposition-Thermal Oxidation and Spray Pyrolysis

Tin oxide films have been prepared by physical vapor deposition of Sn followed by thermal oxidation and by spray pyrolysis of SnCl 4 or SnCl 4 ‚5H 4 O mixed with CH 3 OH. Phase changes and surface morphologies during the syntheses were monitored by X-ray diffraction and scanning electron microscopy. Electrical resistance and UV-visible transmittance of tin oxide films prepared by both methods were measured. The peak shapes of the Auger Sn M 4 N 45 N 45 transition of the prepared tin oxide films were compared to those of commercial SnO and SnO 2 and used to determine rough values of the oxidation state of Sn. Oxygen/tin ratios in the films were determined from analyses of scanning Auger microprobe and X-ray photoelectron spectroscopy and are all less than 2. Auger depth profiles with thermally oxidized tin oxide films on glass substrates show an overlapping region between the tin oxide film and the substrate. These films were tested as sensors for CH 2 Cl 2 in O 2 . The mixed phase (SnO‚SnO 2 ) tin oxide films prepared by temperature-programmed thermal oxidation of Sn showed better sensing behavior to CH 2 Cl 2 than single phase (SnO or SnO 2 ) films.

The effect of incubation and aging on cassiterite type tetragonal rutile SnO 2 nanocrystals employing green synthesis technique has been investigated. The incubation and aging affected the compositional and morphological properties of SnO 2 and not influenced the structural properties of nanocrystals. The incubation and aging further influenced the particle shape and size of the obtained product. XRD results of the obtained product unambiguously revealed the cassiterite type tetragonal rutile phase of SnO 2 nanocrystals. The characteristic Raman peaks observed at 249, 476, 631 and 773 cm -1 were respectively revealed infrared active (E u ), Raman active (E g ), (A 1g ) and (B 2g ) vibration modes of pure tetragonal rutile SnO 2 structure. 3d 3/2 and 3d 5/2 of XPS peaks observed at 496 and 487 eV was clearly revealed the Sn 4? state in tetragonal rutile structure. The obtained TEM micrographs clearly revealed that the grain size and agglomeration was increased at higher incubation and aging treatments.
