The development and characterisation of large area inorganic-organic hybrid X-ray imagers

“SilverRay有限公司是一家初创公司，其主要目标是利用大面积高灵敏度宽带X射线探测器开发的技术。这种专有技术已被证明其灵敏度比传统的有机检测器高2-3个数量级;同时在低电压下工作，并提供对非平面表面的出色适应性。受专利保护的探测器活性材料由一种“X射线敏感油墨”组成，该油墨含有有机材料和无机纳米颗粒的互穿网络。“X射线敏感油墨”可用于在任何基底上镀膜，特别是对柔性探测器没有限制。到目前为止，小面积探测器（面积< 1 cm 2）已经开发出，目前正在由SilverRay有限公司进行放大。挑战在于在整个设备上以及随后在像素与像素之间的厚膜中产生均匀的组分混合物。大面积涂布的薄膜将与A4 I合作伙伴一起沿着进行表征，以便更好地了解如何优化X射线敏感油墨及其制造工艺。该项目的成果将有助于该公司更好地了解优化探测器有源层的路线，这将导致更高性能的成像器和更快的响应时间，这将导致更高规格的探测器。"

"SilverRay Ltd is a start-up company whose primary goal is to exploit the technology developed in large area high sensitivity broad-band X-ray detectors. This proprietary technology has been demonstrated to be 2-3 orders of magnitude higher in its sensitivity than the conventional organic detectors; while operating at low voltage, and offer excellent conformability to non-planar surfaces. The detector active material that has been patent protected consists of an 'X-ray sensitive ink' containing an interpenetrating network of organic material and inorganic nanoparticles. The 'X-ray sensitive ink' can be used to coat films over any substrate, especially without constraints for flexible detectors. Thus far, small area detectors (area < 1 cm2) have been developed with the scale-up currently being conducted by SilverRay Ltd.Challenges lie within the production of a uniform component mixture in a thick film across the device and subsequently between pixel to pixel. Films coated over large area will be characterised along with the A4I partners, to have a better understanding on how to optimise the X-ray sensitive ink and its fabrication processes for manufacture. The outcome of this project will facilitate the company to have a better understanding on routes to optimise the active layer of the detector which would lead to higher performance imagers and faster response times, which will lead to higher specification detectors."
