Abstract

The plasmonic coupling of photoactive molecules and random arrangements of metal nanoparticles on a transparent substrate is demonstrated. It was observed that the triggering of the molecules by UV irradiation shift the plasmon resonance of the gold nanoparticles. In fact, UV irradiation of metal nanoclusters covered with thin layer of Spirooxazine doped polystyrene split the resonance dip in transmission spectra in which the wavelengths difference between the photo-induced divided dips can reach up to 80nm. The origin of the observation attributed to the coupling of the activated molecule resonance with that of the localized plasmon of the nanoparticles. The possibility of the dynamic control of the coupling between the particles and molecules can pave the way for application of plasmonic system in new optoelectronic devices.
