Bridge-assisted ultrafast interfacial electron transfer to nanocrystalline SnO2 thin films

Article Abstract:

A systematic and quantitative investigation of the relative rates of photoinduced interfacial electron transfer as a function of methylene bridge length in the short-bridge limit is accomplished. In the study conducted, the ultra fast infrared spectroscopic investigation of electron injection from a rhenium complex to a SnO2 nanocrystalline film as a function of bridge length is discussed. A novel time-scaling technique to compare kinetic traces allowed the comparison of the nonexponential injection times.

Bridge length-dependent ultrafast electron transfer from Re polypyridyl complexes to nanocrystalline TiO2 thin films studied by femtosecond Infrared spectroscopy

Article Abstract:

A series of studies are designed to investigate how the electron injection rate from the sensitizer to the semiconductor thin films depends on the sensitizer, the semiconductor materials, and their interaction. The electron injection time of a series of Re dyes depended strongly on the electronic coupling between the dye and the surface of TiO2.

Photoelectrochemical and optical properties of nitrogen doped titanium dioxide films prepared by reactive DC magnetron sputtering

Article Abstract:

The nanocrystalline porous nitrogen doped titanium dioxide (TiO2) thin films were prepared by reactive DC magnetron sputtering. These studies showed that the films were porous and displayed rough surfaces with sharp, protruding nodules having a crystal structure varying from rutile to anatase depending on the nitrogen content.
