- Abstract
- Visible fluorescence is produced using an argon-ion laser for excitation in sooting methane/air and methane/oxygen diffusion flames. This emission is attributed to small (two to four ring) polycyclic aromatic hydrocarbons, as suggested by previous studies. The key finding in the present investigation is that the fluorescence spectra can be altered dramatically by changes in the flame stabilization conditions.
