摘要
一种新型柔性 X 射线传感器已经研制成功，这种传感器采用垂直结构，其活性层是在苯乙烯-乙烯-丁二烯-苯乙烯（SEBS）中掺入次要的 6,13-双（三异丙基硅烷基乙炔基）并五苯（TIPS-pentacene）。由于混合活性层中较高的衰减系数和光电流增益效应，次要的 TIPS-pentacene 提高了 1137.2 μCGyair-1 cm-2 的灵敏度和 47.91 nGyair s-1 的低检测限。这种有机探测器的稳定性和灵活性归功于 SEBS 的可塑性和 TIPS-pentacene 的封装。这项研究成果凸显了未来高性能创新型柔性高灵敏度直接 X 射线探测器的开发潜力。
High sensitivity flexible organic X-ray detectors with minor TIPS-pentacene/insulator polymer blend active layer
A new class of flexible X-ray sensor in which there is a vertical structure with the active layer of minor 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-pentacene) blending into styrene-ethylene-butadiene-styrene (SEBS) has been developed. The minor TIPS-pentacene to enhance the sensitivity of 1137.2 μCGyair−1 cm−2 and low detection limit of 47.91 nGyair s−1 because of the higher attenuation coefficient and photocurrent gain effect in the hybrid active layer. The stability and flexibility of this organic detector are attributed to the plasticity of SEBS and encapsulation of TIPS-pentacene. This work highlights the potential exploitation of high-performance future innovative flexible and highly sensitive direct X-ray detectors.
