Abstract
Photochromic materials produced from polymethylmethacrylate lose their photochromic properties through time. It has been discovered that irradiation of such materials resurrects the lost properties completely. The restoration occurs under irradiation with electrons at a fluence of 5.0 multiplied by 1011 cm-2 or with gamma rays at a dose of 500 Gy. Time-resolved spectroscopy has shown that the photochromic state in the materials arises in less than 5 ns while the return to normal state occurs in 0.5 s.
