Abstract

The photophysical and lasing properties of a benzo-fused pyrromethene dye that is capable of being pumped by a diode or dye laser at relatively long wavelengths have been investigated for liquids and for a solid matrix, poly(methyl methacrylate) (PMMA). Fluorescence data, including quantum efficiency and lifetime, have been obtained. The dye emission, that is centered around 690 nm, shows good quantum efficiency as compared to other NIR dyes such as oxazine 1 or rhodamine 800. Photostability in organic solvents as well as the survivability of the dye under conditions of radical polymerization have also been investigated.
