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(φISC)、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(φΔ)、氧的单线态寿命(τ0)。ISC和φΔ的值约为1，τT的值在8～60 μs范围内，τ0的值为20 μs。
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.
