| Abstract: | Reverse saturable absorption of a novel molybdenum complex of fullerene (η2-C60) Mo(CO)2(o-phen)(DBM)·2C6H6·C5H12 has been investigated under irradiation of 10 ns laser pulses at 532 nm. An enhancement of the optical limiting behavior was observed in comparison with C60. An explanation based on the enhanced triplet-state absorption caused by the intra-molecular charge transfer was predicted. The relationship between the clamped laser fluence and low-intensity transmissivity, or the concentration of the solution, was also investigated and a linear dependence was revealed. |
