Paper Abstract

When certain molecules are doped into polymers, they are photo-chemically more stable to photodegradation than the same molecule in liquid solution or crystalline form. Furthermore, such composite materials are also found to self heal after photo-damage when they are stored in the dark. Repeated laser cycling of these dye-doped polymers make them more immune to future photodegradation. In parallel, it has been observed that electrooptic devices made with poled dye-doped polymers become more robust upon irradiation by gamma-rays. In the present work, we combine both gamma radiation and laser cycling and find that the synergism between the two processes may result in more robust materials.
