Abstract: A Nd:YAG pulsed laser was used to excite photosensitizers to induce the generation ofsinglet molecular oxygen in sclution. The lifetimes of O2 (1g) in various solvents weredetermined by monitoring the phosphorescence at 1270 nm. Experimental results reveal thatthe phosphorescence lifetime of singlet oxygen in solution depends mainly on the propertyof solvents used.

Key words: Singlet oxygen, Phosphorescence lifetime
