Abstract
Thin films based on fullerene-containing polyimides COANP and PNP were stud ied using methods of dynamic holography under conditions of Raman-Nath diff raction. A significant increase in the diffraction efficiency of the fuller ene-containing samples was detected, and the threshold of the transition fr om phase grating to amplitude grating was determined. The qualitative expla nation of the results is based on the spectral features and the thermal pro perties of the systems under study. (C) 2000 MAIK "Nauka/Interperiodica".
