"LIIscience.org exists to foster communications about the physics and chemistry of laser-induced incandescence (LII) of nanoparticles. The focus is on aspects of making this powerful diagnostic quantitative.

Laser-induced incandescence (LII) is an in situ method of measuring aerosol particle volume fraction, primary particle sizes, and other thermophysical properties in flames, during gas-phase nanoparticle synthesis, and in aerosol streams more broadly. The technique is prominently used to characterize soot. [1]

The LII method involves rapidly heating soot residing or passing within a laser beam path using a high energy (~100 mJ) pulsed laser source with duration typically less than 20ns. Elemental carbon particles (soot) interacts with the laser beam absorbing light which is converted into heat and increases the particle temperature.

Applied Physics B - Laser-induced incandescence (LII) is a widely used combustion diagnostic for in situ measurements of soot primary particle sizes and volume fractions in flames, exhaust gases,...

Laser-induced incandescence (LII) is a non-intrusive method of measuring soot particle volume fraction and primary particle sizes in flames. Not only restricted to flames, this technique is recently used for characterization of car engine exhaust , …
