The results showed that ZnSe might be a promising gas sensor material if it is used at room temperature. The response of the ZnSe nanowires to 50 ppb–5 ppm NO2 at room temperature under dark and UV illumination conditions were 101–102% and 113–234%, respectively. The responses of the ZnSe nanowires to 5 ppm NO2 increased from 102 to 234% with increasing UV illumination intensity …
Problematik chemischer Sensoren. Das Gebiet der chemischen Sensoren ist relativ jung. Während Sensoren zum Messen physikalischer Größen wie beispielsweise Temperatur, Druck und Beschleunigung wasser und luftdicht verschlossen sind, steht ein chemischer Sensor wie der Gassensor in direkter Wechselwirkung mit seiner Umgebung. Dadurch ist er auch wesentlich …
