A simplified quantitative model of chemiluminescence intramicellar sensitization is proposed, based on the analytical solution of Forster’s energy transfer function for donor–acceptor pairs residing on micellar spherical surface. To test the usab

Buckminsterfullerene, C 60 , exhibits photo-, radio- and sonostoragechemiluminescence. Photolysis, radiolysis or sonolysis results in stable products, while subsequent oxidation of the reaction mixtures, constitutes the chemiluminescence step. Beside

A sensitive and simple method for measuring antioxidant activity was developed, based on antioxidant-dependant quenching of the chemiluminescence (CL) generated from photolyzed acridine and methanolic potassium hydroxide. This method was used to eval
