报道采用调QYAG倍频光(532nm)研究C_(60)/C_(70)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C_(60)/C_(70)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。
The experiment on the optical confinement of C_ (60) / C_ (70) toluene solution by QYAG doublet conversion (532 nm) was reported. The results show that when the energy of incident light is low, the energy of transmitted light changes linearly with the energy of incident light, which obeys Beer’s law. For higher energy of incident light, there is a slowly changing area of transmitted light. When the incident light energy increases beyond a certain After a threshold value, the transmitted light energy remains constant. This shows that the C 60 / C 70 toluene solution has a good light energy limiting effect. The experiment also studied the effect of triplet quenching and solution concentration on the light confinement effect.
