Low Temperature Volatile-Organic-Compound (VOC) Sensor Based on Tungsten Oxide Nanorods

Y.S. Kim, Y.T. Kim and K. Lee
Electronics and Telecommunications Research Institute (ETRI), KR

Keywords:
tungsten oxide nanorod, gas sensor

Abstract:
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 [1]. 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).
