Ever since X-rays were discovered by Wilhelm Röntgen in 1895, they have become a standard in medical imaging.

By using 3D aerosol jet-printing to put perovskites on graphene, scientists at EPFL have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost and health hazard of medical imaging devices.

‘Game Changer' Perovskite Can Detect Gamma Rays Scientists at EPFL have developed a game-changing perovskite material that can be used as a cheaper and highly efficient alternative to gamma-ray detectors. Perovskites are materials made up of organic compounds bound to a metal. Propelled into the forefront of materials’ research because of their structure and properties, perovskites are earmarked for a wide range of applications, including in solar cells, LED lights, lasers, and photodetectors. That last application, photo – or light – detection, is of particular interest to scienti...

New Perovskite Material Could Serve as Cheaper, Better Gamma-Ray Detector Written by AZoMDec 10 2020 Perovskite materials are formed of organic compounds linked to a metal. These materials occupy the forefront of materials research due to their structure and properties and are suitable for an extensive array of applications, such as lasers, solar cells, photodetectors and LED lights.
