FLAM3 What are Lichtenberg Figures, and how are they Made? Other interesting properties: fluorescence, solarization, birefringence, and discharge-free zone When acrylic is irradiated by high-energy electrons, it glows a brilliant blue-white color. Radiation chemistry studies suggest that this is mainly due to luminescence that peaks at a wavelength of about 435 nm. However, acrylic also generates fainter glows from x-ray fluorescence , and Cherenkov radiation . The exact light-producing mechanisms for electron-irradiated PMMA are not fully understood. Newly-irradiated specimens develop an amber-colored layer in the region between the surface(s) that were irradiated by the electron beam and the discharge layer. Called solarization, it appears to be caused by interactions between high speed electrons and the acrylic's molecular structure. underneath the mask. Most of our specimens turn a beautiful lime-green color immediately after irradiation. It has also been discovered that the solarization layer is fluorescent. After we discharge a specimen,
