photoconductor ozone sensor

amount of ozone in the atmosphere, a key player in global warming. The amount of ozone in the atmosphere is directly dependent on the amount of NOx. Consequentially, carbon monoxide affects the levels of NOx found in the atmosphere. Global levels of carbon monoxide have shown an upward trend until the 1980’s when they took a downward turn, mainly due to automobile and industrial ...

Ozone is a triatomic form of oxygen, meaning that the molecule, ozone, is made up of 3 oxygen atoms. Unlike oxygen, ozone is a visible gas with a light blue color at very high concentrations. At low concentrations ozone is colorless. Ozone also has a distinct odor that is noticeable at very low levels and may be associated with a “clean” smell, at higher levels ozone has a very pungent ...

Injection of surface charge into the photoconductor is prevented by the surface blocking layer. The aSiC:H is of low quality, with a high midgap density of states. Surface charge will be trapped in these midgap states. The corona discharges produces oxygen ions and ozone, which may react with the photoconductor [634].
