Photoinduced birefringence in thin azopolymer films recorded at different temperatures
2016
Bulgarian Chemical Communications
unpublished
In this work we investigate the dependence of characteristics of polarization recording and erasure in thin azopolymer films on the starting temperatures of the sample. Polarized light from DPSS laser with wavelength 444 nm is used for recording of photoinduced birefringence. For erasing the records, thermal method is applied. Birefringence is successfully recorded at different starting temperatures from 25 to 100°C. 3D graphics for visualization of the experimental data are presented.
