Paper Abstract

C60 and C70-doped organic thin films (polyimide, 2-cyclooctylamino-5-nitropyridine, N-(4-nitrophenyl)-(L)-prolinol, Mg-phthalocyanine nanoparticles) and the polymer-dispersed liquid crystal compounds based on them have been studied under a laser irradiation at wavelengths of 532, 805, 1047, and 1315 nm. Mechanisms of the optical limiting effect in the fullerene-doped pi-conjugated organic systems have been discussed. Besides the reverse saturable absorption, an additional absorption due to complex formation has been established to be responsible for the phenomena mentioned above. It has been noticed that fullerene-doped organic structures can be used to attenuate the laser power in the visible and near infrared spectral ranges.
