nano-crystalline cu-doped zno thin film gas sensor for co

H2S gas sensing properties of nanocrystalline Cu-doped ZnO ...

The sensor response and selectivity in relation to, operation temperature, Cu doping concentration and the gas concentration has been systematically studied. A significant response (∼) towards 20 ppm H2S at 523 K operating temperature is observed for the 4 wt% Cu-doped ZnO. The Pd-sensitized 4 wt% Cu doped ZnO film exhibits improved sensing characteristics with good stability.

Nano-crystalline Cu-doped ZnO thin film gas sensor for CO ...

A Cu-doped ZnO (CZO) film was prepared on a glass substrate by co-sputtering using ZnO and Cu targets. The CZO film possessed a columnar structure consisting of small crystals with an average grain size of around 5 nm. The CO-sensing properties of the CZO film were tested at operating temperatures of 150, 300, 350 and 400 °C. It was found that CZO-based sensor exhibited the highest ...

nanocrystalline Co doped ZnO shows a better sensitivity to the gases (ethanol and acetone) of less than 100 ppm concentration. In this approach, we try to study the high temperature sintering effect on sensor performance of ZnO and indium doped ZnO nanopowders for detection of the low concentrations of acetone that may cause narcotic effects.

Al-doped ZnO for highly sensitive CO gas sensors ...

The sensors based on Al-doped ZnO exhibited a higher response than the pure ZnO sample, allowing the detection of CO at sub-ppm concentrations in air. The enhancement in sensing properties was discussed in terms of the characterization and electrical data. Abstract Al-doped ZnO (AZO) nanoparticles have been prepared using a modified sol–gel technique. The as-prepared AZO …
