The effect of heavy atoms on the deactivation of electronic excited states of dye molecules near the surface of metal nanoparticles

The influence of a heavy atom and the plasmon field on the efficiency of populating the lowest triplet state (T 1 ) and on the phosphorescence intensity has been studied for fluorescein, 2Br-fluorescein, eosin and erythrosine, which have an increasing number of substituted heavy atoms. We show that...
