Title: Ethanol Sensitivity of Cu{sub 1-x}Sn{sub x}O(x = 0.00, 0.03, and 0.05) Nanoflakes

Abstract

Cu{sub 1-x}Sn{sub x}O(x = 0.00, 0.03, and 0.05) nanoflakes were synthesized by a simple wet chemical method and X-Ray diffraction (XRD) result confirms the monoclinic structure of CuO with no secondary phases due to Sn doping. The scanning electron microscopic images indicate the formation of nanoflakes. The fundamental Raman modes were observed at 273, 318, 610, and 1084 cm{sup -1} for undoped CuO sample and theses modes were slightly shifted towards lower frequency side for Sn-doped samples, which indicates the inclusion of Sn in CuO. In addition, XRD and Raman studies infer the decrease of crystallinity in doped samples, which is reflected in the sensitivity towards ethanol. The ethanol sensitivity (resistivity measurement) increases with ethanol gas concentration and decreases with Sn-doping in CuO nanoflakes.
