Multiple spectroscopic techniques reveal the absorption of light by titanium dioxide

14 April 2017 | News

Titanium dioxide (TiO2) is one of the most promising materials for photovoltaics and photocatalysis nowadays. This material appears in different crystalline forms, but the most attractive one for applications is “anatase”. EPFL scientists have now shed light onto the problem by a combination of steady-state and ultrafast spectroscopic techniques, as well as theoretical calculations.
