| 摘 要： | 利用时间分辨热透镜技术测定了Ｃ６０的三线态量子产额（ＩＳＣ）、三线态寿命（τＴ）以及苯溶液中溶解氧通过猝灭Ｃ６０三线态而生成的单线态氧的量子产额（Δ）、氧的单线态寿命（τ０）。ＩＳＣ和Δ的值约为１，τＴ的值在８～６０μｓ范围内，τ０的值为２０μｓ。

| Abstract: | The quantum yield of triplet formation (φISC) and the triplet lifetime (τT) of C 60 , as well as the quantum yield of singlet oxygen formation (φΔ) by the quenching of the triplet state of C60 and the singlet lifetime (τ0) of oxygen are measured by a time resolved thermal lensing technique. Both φISC and φΔ are nearly unity and the lifetimes of both the triplet C60 and the singlet oxygen are in the range of 8￣60 μs and 20 μs respectively. |
