ENHANCED OPTICAL LIMITING PERFORMANCE OF A NOVEL MOLYBDENUM COMPLEX OF FULLERENE

Reverse saturable absorption of a novel molybdenum complex of fulleren e (eta(2)-C-60) Mo(CO)(2)(o-phen)(DBM) . 2C(6)H(6 .) C5H12 has been in vestigated under irradiation of 10 ns laser pulses at 532 nm. An enhan cement of the optical limiting behavior was observed in comparison wit h C-60. An explanation based on the enhanced triplet-stare absorption caused by the intra-molecular charge transfer was predicted. The relat ionship between the clamped laser fluence and low-intensity transmissi vity, or the concentration of the solution, was also investigated and a linear dependence was revealed.
