On the feasibility of Laser-Induced Incandescence technique for TiO2 nanoparticles analysis

Résumé

This work-in-progress study aims to develop a method to verify the possibility of measuring the Laser-Induced Incandescence (LII) signal from TiO2 nanoparticles. For this, the optical system for LII was first validated on flamegenerated soot particles. Then, spectrally-resolved measurements of laser-induced emission of TiO2 nanoparticleladen aerosol were performed. At 355 nm laser wavelength, the laser-induced emission spectrum presents a response to laser fluence and detection gate delay typical of the black-body radiation, i.e., dependent on the particle temperature. It is concluded that laser-induced incandescence is possible for non-carbonaceous TiO2 nanoparticles.
