【摘要】 报道采用调QYAG倍频光（532nm）研究C₆₀/C₇₀甲苯溶液光限制的实验。结果表明:当入射光能量较低时,样品的透射光能量随入射光能量线性变化,遵从Beer定律;对较高的入射光能量,透射光有一缓慢变化区;当入射光能量增加到超过某一阈值后,透射光能量保持为一定值。这表明C₆₀/C₇₀甲苯溶液有很好的光能量限制效应。实验还研究了有关三重态淬灭及溶液浓度对光限制效应的影响。更多还原

【Abstract】 The optical limiting effect of fullerence C₆₀/C₇₀ was investigated by passing the second harmonic generation （530 nm） of a YAG laser through the solution of C₆₀/C₇₀ in toluene. The output energy of the solution increased linearly with the increment of the input energy at very low energy, while, as the input energy increased continuously, the output energy increased slowly and finally was limited to a certain value. The influence of the triplet state quenched and concentration of the solution on the optical limiting effect was also investigated.更多还原
