Implication

Spectroscopy study demonstrates ultrafast electron transfer from gold nanodots into titanium dioxide nanocrystals, highlighting rapid solar energy conversion pathways.

Key Points

Directly measure the kinetics and transfer yield of plasmon-induced electrons moving from gold nanodots into a titanium dioxide nanocrystalline film.
Utilized femtosecond transient absorption spectroscopy configured with a visible pump and an infrared probe to monitor electron injection in real time.
Tested a material interface composed of 10 nm gold nanodots deposited onto a titanium dioxide (TiO2) nanocrystalline film.
Plasmon-induced electron transfer took place within a reaction time of 240 fs.
The interfacial electron transfer process demonstrated a yield of approximately 40%.
