摘要
非制冷辐射热探测技术的发展使在室温下进行红外探测成为可能,目前的热探测一般采用无机材料。探讨了导电聚合物聚乙烯二氧噻吩:聚对苯乙烯磺酸(PEDOT:PSS)作为非制冷辐射热探测器敏感材料的可行性,研究了其热敏特性和红外吸收特性,制备了PEDOT:PSS 自支撑悬空微桥单元,并进行了初步测试,在室温下,预计该热探测器响应时间约为12 ms,探测度D*可达3×1010 cm?Hz1/2?W-1,在响应时间与无机材料热探测器相当的情况下,探测度高一个量级以上。
Abstract
The development of uncooled radiation thermal detection technology makes infrared detection at room temperature possible. Presently inorganic materials are tended to be adopted for thermal detectors, this paper discusses the possibility of conductive polymer named poly (3, 4-ethylenedioxythiophene): poly (styrenesulfonate) as radiation thermal detector material, studies about the thermal sensitivity and infrared absorption of PEDOT: PSS, fabricates suspended micro-bridge element and does corresponding texts preliminarily. At room temperature, the estimated response time (12 ms) is comparable to thermal detectors and the detectivity D* is estimated to reach 3×1010 cm?Hz1/2?W-1, which is much higher than current thermal detectors.
