摘要
The quenching processes of prompt and delayed fluorescence of hypocrellin A by rareearth ions were investigated. It is demonstrated that the prompt fluorescence of HA can bequenched efficiently by RE in methanol via a static quenching process including a groundstate complex formation. The thermally induced delayed fluorescence of HA can also bequenched effectively by complex formed, which quenching is of dynamic quenching behavior.The fluorescence quenching of HA in various micellar systems which protect the quenchingby the compartmentalization of micelles is discussed as well.
