">The crystals, which blink when exposed to a beam of electrons, could be useful for environmental cleanups, sensors, electronic devices, and solar cells, and the research team will further explore their capabilities." Hmmm, maybe this could make an electron beam detector/tracer/debugger... and/or a substrate or part of a substrate for electron beams to interact with in some way... Perhaps transistors and circuits could be created with electron beams and the right substrate in the future...
