Two dimensional metal nanostructures such as silver nanorods (AgNRs) exhibit a unique surface plasmon resonance (SPR) pattern involving transverse (TM) and longitudinal modes (LM). Such plasmonic near field is observed to have a profound effect on YAG:Ce nanoparticles placed in optimal proximity resulting in an unprecedented blue emission at TM excitation (383 nm). Unembellished YAG:Ce does not fluoresce...
Silver nanoparticles (Ag NP) can behave like optical nano antennas by confining and enhancing the incident electromagnetic field (EM) around them due to localized surface Plasmon resonance (LSPR). Such augmented near field of plasmonic nano antennas has been harnessed to enhance blue fluorescence emission from ZnO nanoparticles optimally conjugated with Ag NPs. Overlapping of LSPR band with excitation...
