文摘
- •
CuO thin film was grown on quartz substrate using sol gel route.
- •
Gas sensing properties of CuO thin film was performed using a quasi-static system.
- •
Excellent response is obtained towards ethanol, methanol, acetone and 2-propanol.
- •
High response (%) and low response time(s) are achieved at optimized temperature.
- •
FFT and PCA were studied to address the cross sensitivity.
