Abstract

The photobleaching of chromophores was analyzed in front of metal film using emitted fluorescence intensity which was obtained from ensemble of chromophores. The photostability dependence was observed on distance from metal surface. The photobleaching occurred at constant rate from excited state which was described in classical elctromagnetic model. The photostability of chromophores was influenced by metal interface by altering excitation rate by local enhancement of electromagnetic field and electromagnetic decay rate.
