  • Patent number: 9929216
    Abstract: A process for fabricating an organic x-ray detector is presented. The process includes forming a layered structure that includes disposing a first electrode layer on a thin film transistor array, disposing an organic photoactive layer on the first electrode layer and disposing a second electrode layer on the organic photoactive layer. The organic photoactive layer includes a fullerene or a fullerene derivative having a carbon cluster of at least 70 carbon atoms. The process further includes disposing a scintillator layer on the layered structure at a temperature greater than 50 degrees Celsius. An organic x-ray detector fabricated by the process is further presented. An x-ray system including the organic x-ray detector is also presented.
