Abstract
Fulgide Aberchrome 670-doped polymer films were studied. Two approaches were considered: photochemical characterization and holographic recording.
In PMMA matrix, the closed form presents a maximum of absorption centered at 525 nm upon irradiation at 365 nm. We have determined the photoreaction rate constants kUV and kVIS respectively for the coloring and bleaching process: kUV=1.2×10−3 s−1 and kVIS=11.1×10−3 s−1. Photochemical fatigue resistance in different polymer matrices was investigated. We found a loss of 9, 11, 13 and 35% respectively in PS, CA, PMMA and PVK. Concerning holographic recording, we obtained diffraction efficiency η=0.65% in PMMA films 30 µm thick.
