Halide Perovskite-Polymer Composites for High Energy Photon Detection and Protection

An FSU researcher created a novel material comprised of halide perovskite crystals embedded in a polymer matrix for radiation blocking and detection. The material is lightweight and lead free. Other materials require expensive and long manufacturing processes, but this novel material can be manufactured in a variety of ways such as solution-based drop casting, hot pressing, melt extrusion, injection molding, and 3D printing, to save time and money. Electrodes can be embedded in the material for passive and accurate x-ray and gamma-ray detection.  

Third party independent testing has shown that the material is 50% more effective than current state of the art radiation blocking technology. These semiconducting nanocrystals are uniformly dispersed in the polymer matrix to not only block radiation but also detect high energy radiation.
