Perovskites: Hybrid materials as highly sensitive X-ray detectors

New bismuth-based organic-inorganic hybrid materials show exceptional sensitivity and long-term stability as X-ray detectors, significantly more sensitive than commercial X-ray detectors. In addition, these materials can be produced without solvents by ball milling, a mechanochemical synthesis process that is environmentally friendly and scalable. More sensitive detectors would allow for a reduction in the radiation exposure during X-ray examinations.

X-ray imaging is indispensable in medical diagnostics and material characterisation. To generate an image, a detector converts X-rays that pass through the object into electrical signals. Higher detector sensitivity enables lower radiation doses, which is particularly important in medical applications.
