By using femtosecond transient absorption spectroscopy with visible pump and IR probe to observe generation of injected electrons, we could directly observe plasmon-induced electron transfer from 10 nm gold nanodots to TiO2 nanocrystalline film. It was revealed that the reaction time was within 240 fs and the yield was about 40%.
通过使用可见泵浦和红外探测的飞秒瞬态吸收光谱来观察注入电子的产生，我们能够直接观测到等离子体激元诱导的电子从10纳米金纳米点转移到二氧化钛纳米晶体薄膜。结果表明，反应时间在240飞秒以内，产率约为40%。
