| dc.description.abstractEn | We have performed single-shot time-resolved reflectivity measurements of the photo-reversible phase transition between λ- and β-phases of Ti3O5 nanoparticles at room temperature. These phase transitions are induced using nanosecond and millisecond laser pulses and are revealed by Raman spectroscopy. Upon nanosecond pulsed excitation, the λ- to β-phase transition is detected in about 900 ns, whereas the β- to λ-phase transition is noticed in less than 20 ns. The λ- to β-phase transition induced by quasi continuous wave laser happens on the millisecond time scale. We propose a scenario that accounts very well for the observed phenomena. | |
