- Аннотация: We report the observation of picosecond kinetics (ps) of the luminescence decay in Ag nanodusters dispersed in oxyfluoride glass host. Calculated normal oscillator strengths for the Ag nanoclusters cannot account for 'such fast kinetics of luminescence, suggesting its cooperative origin. This confirmed by the concentration dependence of the intensity of picosecond component. Further analysis shows that cooperativity does not relate to conventional superradiance but is rather mediated by plasmons of dispersed Ag nanopartides around which Ag nanodusters coordinated. The plasmon Dicke effect may be applied for the generation of picosecond pulses across a wide range of wavelengths in these glasses.
