Metal ion induced room temperature phase transformation and stimulated infrared spectroscopy on TiO2-based surfaces

Raman and infrared spectroscopy are used to demonstrate (1) the high spin metal ion induced room temperature transformation of anatase to rutile TiO2 and (2) the phenomena of stimulated IR spectroscopy induced by simultaneous nitrogen doping and high spin metal ion seeding of a TiO2 nanocolloid lattice.
