摘要: Understanding how nanoscale interfaces affect electrical and optical properties of multifunctional nanocrystal heterostructures is paramount importance for their technological application. In this context, we investigated the ultrafast carrier dynamics rodlike gold–iron oxide heterodimers, in a spectral region close to surface plasmon resonance frequency, by means broad-band transient absorption spectroscopy. We found that electron–phonon relaxation time independent morphology iron domain. Moreover, revealed shift which can be related charge transfer at interface between gold oxide.
