| Outline of Final Research Achievements |
This study attempted to visualize reversible X-ray radiation by using a polymer-based composite film and fiber. The composites film was consisted of a photochromic dye (6-nitroBIPS), BaFCl:Eu particles, and polycarbonate (PC). On the other hand, in the case the composite fiber, a poly-(L-lactic acid) (PLLA) having a good dyeable property was used. The 6-nitroBIPS/BaFCl:Eu PC composite film successfully showed a high visualization property to the synchrotron radiation of SPring-8. Upon X-ray exposure for 73 s (a dose corresponding to 7.41 Gy), the color of the dyed composite fiber reversibly changed from white to pale purple.
