The Uses of Coumarin 30

Coumarin 30 is a laser dye for pulsed and CW operation.

The Uses of Coumarin 30

C30 can form a thin film on p-silicon (p-Si) semiconductor, which can be used to fabricate the aluminum/C30/p-Si based diodes. It can be used as a donor with fluorescein as an acceptor to study the time resolved fluorescence resonance energy transfer (FRET).

General Description

Coumarin 30 (C30) is a laser dye that has a fluorescence yield that tends to unity, which can be potentially used in optical communications and sensors. It is highly stable on the spin coating and shows high quantum efficiency upon low concentration doping.
