摘要：

The sintered bulk CuCrO2 and thin film were prepared by sol-gel and pulsed laser deposition, respectively. They show rhombohedral 3R structure, wide band gap and p-type semiconducting properties. These properties are similar with those of CuAlO2, which has been found to be a promising candidate for inexpensive p-type and transparent ozone sensor. In this study, the room temperature ozone sensing properties of the sintered bulk CuCrO2 and thin film were investigated. Furthermore, transparent p-type semiconductor CuCrO2 shows selective and reversible response to ozone at room temperature. This study suggests that CuCrO2 can be another promising candidate for parent materials of room temperature ozone sensor besides CuAlO2. (C) 2009 Elsevier B.V. All rights reserved.
