Figure 6From: Synthesis and high sensing properties of a single Pd-doped SnO2 nanoribbonSensitive responses to ethanol of a single Pd-doped SnO 2 nanoribbon tested at 230°C. (a) Responses of a Pd-SnO2 NB to ethanol at 100 ~ 500 ppm at 230°C. (b) Responses of a Pd-SnO2 NB to ethanol at 1 ~ 1,250 ppm at 230°C. (c) The log(Rs - 1) versus log(C) curve and its fitted line.Back to article page
