We have systematically used Electron Paramagnetic Resonance (EPR) to understand the nature of excess electron centers in Titanium dioxide and to classify their spectroscopic features. Excess electrons in TiO2 (probably the most important photoactive oxide) have been generated either by photoinduced charge separation or by reductive treatments and are stabilized in the solid by titanium ions which reduce to paramagnetic Ti 3+ . These are monitored by EPR and classified on the basis of their g… CONTINUE READING
