Plasmon-enhanced stimulated emission of chromene dye

Effect of silver nanoparticles on spontaneous and stimulated emission of chromene- 3 in ethanol solution is studied. It is established, that upon laser photoexcitation of solution the spontaneous fluorescence is observed, which with increasing of pumping energy transforms in stimulated emission. The...

Description
Summary:Effect of silver nanoparticles on spontaneous and stimulated emission of chromene- 3 in ethanol solution is studied. It is established, that upon laser photoexcitation of solution the spontaneous fluorescence is observed, which with increasing of pumping energy transforms in stimulated emission. The increasing of fluorescence, stimulated emission and lasing threshold was observed upon addition of silver nanoparticles. The dependence of intensity of lasing of silver concentration correlates with data of fluorescence.
