Probing UPD-induced surface atomic rearrangement of polycrystalline gold nanofilms with surface plasmon resonance spectroscopy and cyclic voltammetry

Article Abstract:

The surface plasmon resonance (SPR) is used as a novel probe tool in combination with electrochemistry to study in situ the effect of Ag underpotential depostion (UPD) on the SPR response of the electroless plated gold thin-film electrode. It is found that the repetitively electrochemical UPD and stripping of Ag have a dramatic effect on both the optical and electrochemical properties of the Au nanofilms, as evaluated by using both in-situ SPR and electrochemical measurements.

Relationship between the nanostructures and optical properties of CeO2 thin films

Article Abstract:

The study focuses on correlations between microstructures and optical properties of expitaxial CeO2 thin films that are grown using metal organic chemical vapor deposition on two different single crystal substrates of Al2O3 and TiO2. The results revealed that well ordered Ceo2 films with an abrupt optical absorption and high visible transparency can be grown at low temperature on Al2O3.
