论文摘要
我们进行了对普通高度吸收碳基材料的光声疾病的实验比较。对比较的参数与光声探测器和傅立叶变换红外（FTIR）光谱相关：我们涵盖了从可见的红色到远红外（633 nm至25 um）的广泛波长范围（633 nm至25 um）以及低声频率的状态（<1 kHz）。研究的材料包括蜡烛基于烟灰的涂层，黑色油漆涂料和两种不同的碳纳米管涂层。其中，低成本的烟灰吸收器显然在整个测量范围内产生了最高的光声反应。
We present an experimental comparison of photoacoustic responsivities of common highly absorbing carbon-based materials. The comparison was carried out with parameters relevant for photoacoustic power detectors and Fourier-transform infrared (FTIR) spectroscopy: we covered a broad wavelength range from the visible red to far infrared (633 nm to 25 um) and the regime of low acoustic frequencies (< 1 kHz). The investigated materials include a candle soot-based coating, a black paint coating and two different carbon nanotube coatings. Of these, the low-cost soot absorber produced clearly the highest photoacoustic response over the entire measurement range.
