Keywords: tungsten oxide nanorod, gas sensor
Tungsten oxide sensors were fabricated by using highly crystalline and homogeneous WO2.72 nanorods, previously synthesized and characterized with average 75-nm length and 4-nm diameter . They provide unique opportunities for investigating the effects of size-controlled tungsten oxide nanorods on vapor detection. Here, we report excellent sensing ability of the nanorod sensors at low operation temperature, even ambient temperature, upon exposure to volatile organic compounds (VOCs).
