Effect of NiO addition on the DPGME sensing properties of SnO2 thin film |
| 초록 |
A SnO2-based thin film (S_TN) and thick film (S_TK) sensors prepared by ion sputtering and screen printing methods, respectively, to investigate sensing behaviors of S_TN and S_TK sensor for the detection of 0.1 ppm DPGME. The S_TK sensor shows a particle size of 30 to 200 nm and a thickness of 10 µm. While, the particle size and thickness of S_TN sensor were about 60 nm and 100 nm, respectively. The S_TK sensor showed a low sensor response of about 29 % for the detection of 0.1 ppm at 350°C, while the S_TN sensor showed high sensor response of about 41 %. In particular, S_TNNi(I) sensor, which was prepared by dropping nickel nitrate solution on the SnO2 thin film prepared by ion sputtering showed the highest sensor response of about 53 % and complete recovery properties. The responses of S_TNNi(I) sensor increased almost linearly at 0.05 ppm and 0.5 ppm, and its optimum temperature required for the detection of DPGME was 350oC. we will discuss effects of preparation methods and promoters on the sensing properties of SnO2 thin film sensor for DPGME gas. |
