化学传感器陶瓷点缺陷及其应用

Point Defects and Applications of Chemical Sensors Ceramics

化学传感器是一种重要的绿色传感器,在环境保护、催化合成等领域的工业过程和质量控制方面有着广泛应用.近来由于其在临床诊断、安全警报、缉毒安检和反恐防恐等方面的特殊功用,倍受重视而得到了很大的发展.本文就当今化学传感器陶瓷研究的一个热点-点缺陷与周围环境物理-化学交互作用,如点缺陷在氧化、还原和掺杂以及光、电、颜色等化学环境变化所导致的新应用和新进展作系统论述,以期有助于今后我国在该领域的基础研究和原创性、开拓性绿色事业研究的开展,在当前全球性经济危机下,具有特别重要的意义.

Chemical sensors, an important green sensor, in view of the relation of the structure-sensitive and the physico-chemistry interaction with the surrounding environment for the point defects on the change of chemical surrounding in redox, additive and optical-electro-color fields are the key of the new applications and new developments in this paper. The knowledge of how the point defects influence the ceramics/device performance was revealed and provides very useful tools for understanding their basic characteristics and to open up their potentiality of the new applications in the near future.
