In2O3- and SnO2-Based Thin Film Ozone Sensors: Fundamentals

It is necessary to note that thick film and thin film technologies are frequently combined to produce planar ozone sensors, especially in laboratory investigations. For example, gas-sensing polycrystalline SnO 2 and In 2 O 3 layers may be prepared via thin film technologies (, spray pyrolysis, magnetron sputtering, laser ablation, or chemical vapor deposition), while the heaters are formed with thick film …

UVC Facts (FAQ) – Steril Aire

But what about Ozone? UVV or Vacuum UV light refers to another wavelength in the ultraviolet spectrum. Some UVC devices also produce light in this wavelength. The manufacturers of these devices promote UVV as an added tool for IAQ control, saying that UVV attacks microorganisms, chemicals, and odors. While this may be true, it is important to understand that UVV (unlike UVC) will also “attack” …
