Vibronic Fine Structure Found in the Blue Luminescence from Silicon Nanocolloids

Well-isolated vibronic fine structures are observed on the ultraviolet-visible photoluminescence spectrum from suspended silicon nanometer-sized particles in an organic fluid. Progression analyses of these structures and IR data show that these structures come from various local vibrational modes th...

Description
Summary:Well-isolated vibronic fine structures are observed on the ultraviolet-visible photoluminescence spectrum from suspended silicon nanometer-sized particles in an organic fluid. Progression analyses of these structures and IR data show that these structures come from various local vibrational modes that couple with the localized electronic state of surface chemical species related to oxygen.
