“…Nevertheless, it is doubtful if fully dense films are achievable, without melting the metal oxide, as disintegration occurs before. [79] Some methods, such as vapor-fed aerosol flame synthesis (VAFS: Figure 7) are also able to produce semiconductor nanoparticles of controlled size and crystallinity [80] but to date have not been utilized for direct deposition of sensing films. [81][82][83] …”

“…However, high-temperature (> 1000 8C) annealing may also not be applicable as it was reported that highly porous, particulate films tend to disintegrate above a given sintering temperature. [79] Recently, stabilization of FSP-made SnO 2 films was achieved by rapid (30 s) in situ annealing with a particlefree flame. [51] The SnO 2 crystal size was not altered while the film porosity was reduced drastically, thus increasing the film mechanical stability.…”

“…Furthermore, the in situ annealing of micropatterns can be applied to a wide range of nanoparticle compositions and coating processes such as filtration [21] and electrophoretic deposition, [2] since it rapidly transforms highly porous layer or film morphologies to denser ones firmly adhering to the substrate. This is a key process design feature that facilitates the development of large-scale nanoparticle deposition methods.…”

“…Es ist aber zweifelhaft, ob eine Herstellung vollständig dichter Filme ohne ein Schmelzen des Metalloxids möglich ist, da bereits vorher eine Zersetzung eintritt. [79] Halbleiternanopartikel mit einer kontrollierten Größe und Kristallinität können auch durch andere Methoden wie die Flammenaerosolsynthese (vapor-fed aerosol flame synthesis, VAFS; Abbildung 7) erzeugt werden, [80] aber diese Verfahren wurden bisher noch nicht für die Direktabscheidung von Sensorfilmen angewendet. [81][82][83] …”

“…Andererseits könnte auch eine hohe Sintertemperatur (> 1000 8C) ungünstig sein, da hochporöse Partikelfilme ab einer bestimmten Temperatur zum Zerfall neigen. [79] Jüngst gelang die Stabilisierung von FSP-SnO 2 -Filmen durch schnelles (30 s) In-situ-Tempern mit einer partikelfreien Flamme. [51] Die Größe der SnO 2 -Kristalle veränderte sich dabei nicht, aber die Porosität des Films nahm drastisch ab, was den Film mechanisch stabiler machte.…”
